Mud on the Collar

Two supercharged Jaguar XJRs, a century and a half of British insistence that you can be violent and well dressed at the same time, and the case that both of them are now the best money in the classifieds.

By Sloane Whitaker · 38 minute read

There are very few companies on earth that can pull off style, elegance and athleticism all at once, in a tuxedo, without looking like they are trying. A few watch companies get close — Omega, Rolex and Breitling built entire catalogs on the premise that a chronograph should survive 300 meters of seawater and still look correct under a dinner jacket cuff. Fashion has mostly failed. What the industry calls athleisure is athletic wear that has been taught to sit still, which is not the same trick at all. One clothing company has done it properly and done it for decades, and the single garment that proves it is the rugby shirt.

A rugby shirt is designed to be grabbed, twisted, rained on, dragged through mud and then worn to dinner. It is not a compromise between those two lives. It is genuinely good at both, which is far rarer than it sounds, and it is why the thing has survived roughly a century and a half of fashion without ever changing its job.

Only the British would insist on carrying style, class and dignity into the business of getting filthy. There is something close to psychological warfare in it. You turn up to the arena dressed to the nines and the opposition spends the first ten minutes working out whether you know something they do not. Maybe you have a plan. Maybe, if you lose, you intend to lose in something nice rather than in rags. Maybe, if you win, the outfit is a form of respect paid to the man you just beat. Or maybe you are simply that pompous.

They wore red coats into battle, for heaven's sake. Not stealthy. But you have to look good and you have to make a presence.

The honest version is better than the joke. Red was not chosen to hide blood, which is nonsense; blood dries black on red wool. The historian W. Y. Carman put it down to money, culture and luck: red took one dye application where blue took two, so the rank and file wore cheap madder and the officers wore costly cochineal, a small class system rendered in fabric. Then it stuck around out of habit until the rifle settled the argument. British infantry wore scarlet on active service for the last time in the Sudan in 1885.

Cheap, accidental, gorgeous, and kept long past the point of sense. Hold that thought. We are going to need it.

The shirt that survived everything

Wool, then cotton, then a fabric you cannot hold on to

Early rugby kit was wool jumpers over white cotton trousers, because wool was the technical fabric of the nineteenth century in the same way carbon fiber is the technical material of this one. People swam in it; Speedo was still knitting wool trunks in the late 1930s. But wool on a pitch is heavy, it itches, and wet it is basically a weighted vest, so the woolen tops gave way to heavy-gauge cotton. Long sleeves, bold stripes, and best of all a contrasting collar. Cotton breathed. Cotton let men clobber one another in comfort. The gentleman's uniform had quietly become athletic equipment.

Then it escaped the pitch. After the sport's revival in the 1960s and 1970s the rugby shirt became load-bearing preppy infrastructure on Ivy League campuses, which is where Ralph Lauren comes in; he founded his company in 1967, named the menswear line Polo in 1968, and by 1972 was selling the knit shirt that defined the look for fifty years.

The campuses make sense. What makes less obvious sense, and is far better, is that the rugby shirt also went climbing. Yosemite in the late 1960s was full of dirtbag climbers hunting for clothing that could survive granite, and a shirt overbuilt to survive a scrum turns out to meet the same specification. On a winter climbing trip to Scotland in 1970, Yvon Chouinard bought a regulation team rugby shirt to wear on rock. Patagonia's own history explains exactly why it worked, and it is the collar, of all things:

“Overbuilt to withstand the rigors of rugby, the shirt had a collar that would keep the hardware slings from cutting into his neck.”

Patagonia, company history

Chouinard founded Patagonia in 1973 and it has been making rugby shirts more or less ever since. A garment invented so that gentlemen could be violent politely ended up on the side of El Capitan because the decorative collar was, by accident, load-bearing safety equipment. That is the entire thesis of this article and we are eight hundred words in.

The fabric kept moving. Modern jerseys are tight-cut cotton-polyester, and the reason is not comfort: polyester is slipperier and a fitted shirt leaves nothing for a tackler to grab. It is also about water: an old cotton jersey could finish a wet match carrying up to 3 kilograms (6.6 pounds) of it. The traditional shirt even used rubber buttons, so a fistful of collar popped it open rather than tearing them off.

Wool to cotton to polyester. Heavier and honest, then lighter and harder to catch. Remember that sequence too.

So what does any of this have to do with cars

The argument for Jaguar, and the arguments against it

Jaguar is the rugby shirt.

Before you start shouting at the screen: yes, Bentley. Yes, Aston Martin. Those are good arguments and they are not wrong, exactly. But both made expensive objects in small numbers for people who already had money. Jaguar spent decades building fast, beautiful, genuinely quick machinery in volume, for people who had to think about the price of it, which is a different and much harder trick. Bentley only became a serious volume carmaker again in the last twenty-five years, and it took Volkswagen's checkbook to do it.

The royal connection is real but the loose version of it gets repeated constantly, so: Jaguar is not the official State car. Those are the two Bentleys and three Rolls-Royces in the Royal Mews, including the Bentley State Limousine built as a Golden Jubilee gift in 2002, of which exactly two exist. What is true is that Jaguar Land Rover holds a Royal Warrant, granted by King Charles III in 2024 and Queen Camilla in May 2025, and that royals have driven Jaguars privately for as long as anyone can remember. Elizabeth II was photographed at Windsor at the wheel of a green Jaguar X-Type wagon, headscarf knotted under the chin, which is a more persuasive endorsement than any state limousine will ever manage.

Not the official car. The actual car. Which is rather the point.

The line runs from the Mark II — the compact saloon so good at leaving a scene that both the police and the people they were chasing bought them — through the E-Type and the XJ-S, and arrives at the XJR. We covered the early part of that story in The Gentleman Villain and Nine Lives. This piece picks up where those leave off, because the XJR is where Jaguar stopped implying its luxury saloon could be quick and started printing the number on the window sticker.

What the R was doing before it got on a saloon

Le Mans, Daytona, and a badge that had to be earned first

Here is the part that gets skipped, and it is the part that makes the rest make sense. The two letters on the trunk lid were not a marketing department's idea of a sporty suffix. They came off a race car.

Jaguar's Group C and IMSA prototypes were called XJR, starting with the XJR-5 that Bob Tullius's Group 44 team put on a grid at Elkhart Lake in August 1982. Tom Walkinshaw Racing took the program over and the results arrived in a heap: the World Sportscar Championship in 1987, 1988 and 1991; the Daytona 24 in 1988 and 1990; and Le Mans twice, the XJR-9LM of Jan Lammers, Johnny Dumfries and Andy Wallace in 1988, and the XJR-12 of Martin Brundle, Price Cobb and John Nielsen in 1990, the year Jaguar finished first and second. Jaguar's own heritage release puts it plainly:

“The very first Jaguars to bear the R badge were the XJR racing cars which campaigned in the World Sportscar Championship and American IMSA series from 1983... Jaguar decided to develop the R badge officially, and established JaguarSport as a joint venture with TWR to build low-volume, high-performance, R-badged road cars.”

Jaguar Land Rover, “25 Years of Jaguar R Performance Cars,” 2013

Jaguar dates the program from 1983, which is its first full season; the car itself ran in 1982. Sir John Egan said the point of the venture was to “apply the experience we have gained on the racing circuits of the world” to road cars for the enthusiast — a chief executive saying, in the flattest possible English, that they were supposed to smell of the race cars. Then JaguarSport did something wonderfully unsubtle about it. The 1988 XJR-S Le Mans Celebration, 100 cars in Tungsten metallic gray, carried a coachline on each rear quarter panel drawn in the outline of the winning XJR-9, and sill plates engraved with two laurels. It sold out in four days at £38,500, roughly $190,000 in 2026 money. They put the race car on the side of the road car, as a pinstripe. It is the least British thing Jaguar has ever done and it is fantastic.

The badge came down from there. The XJ40-based XJR of 1990 was a JaguarSport conversion with 248 bhp and not much else. The X300 XJR of 1994 was the first Jaguar engineered in-house and the company's first supercharged production car: a 4.0-liter AJ16 straight-six with an Eaton M90 blower, around 320 bhp, 378 lb-ft, and, for 268 lucky people worldwide, a Getrag five-speed manual. 6,547 were built. It cemented the concept the way first attempts do — incompletely, and with enormous promise.

Then Jaguar put a V8 in it.

The X308: the hot rod in the good suit

1998–2003 · 370 horsepower · steel · unrepentant

Jaguar had wanted to build an all-new car around the new V8 and Ford said no, so the X308 is the old car's center section with a new engine and new ends bolted to it. That sounds like a compromise and it was. It also produced the best-driving XJ anyone had built to that point, which is the sort of thing that happens when engineers are told they cannot start over.

The XJR got the supercharged version: 4.0 liters, an Eaton M112 Roots blower turning at a 2:1 drive ratio, twin air-to-water charge coolers, 370 horsepower at 6,150 rpm and 387 lb-ft at 3,600. Sport suspension, wider wheels and tires, matte-black window trim everywhere in the world except the United States, where Jaguar decided Americans wanted chrome window frames and rain gutters, and gave them chrome window frames and rain gutters. Body-colored grille surround with a stainless steel mesh insert instead of vanes. Bigger exhaust outlets. A badge on the trunk lid. That is the entire exterior vocabulary of a car that will do 155 mph.

The transmission is a small joke in its own right. It is a Mercedes-Benz W5A580 — the 722.6, the same 580 Nm-rated family Stuttgart was fitting to the E55 AMG at the time. So when the Jaguar lined up against the Mercedes in a magazine comparison, both cars were shifting through the same gearbox. Jaguar worked it through the J-gate: a shift gate shaped like the letter J, introduced on the XJ40 in 1986, with one leg for P-R-N-D and a parallel leg for holding gears manually so you could never overshoot into neutral. It solves a real problem and nobody has ever agreed about it. It survived until the 2008 XF, when a rotary dial rendered it obsolete, and it has been quietly missed ever since.

Instrumented figures and test-car weight from Car and Driver, March 2000. Manufacturer curb weight is quoted at 1,848 kg (4,075 lb).

What it is like, and where that put it

Turn the key and almost nothing happens. It idles quietly, the way a car with walnut on the dashboard is supposed to. Then you lean on it, and a Roots blower does the thing a turbocharger cannot: it is simply there, all of it, from just off idle, and it sings while it works. EVO caught the timing of it exactly — the supercharger “doesn't find its voice until you start to press the throttle deep into the thick carpet,” and from then on it dominates everything. One Car and Driver editor put it better than any of us have managed since:

It does. And on a fast road it is the only warning the car gives you, because nothing else about the car ever raises its voice. The steering is precise and communicative. The ride stays absorbent on 40-series tires. You are doing 90 mph in a library, and the only thing telling you so is a faint mechanical hum from somewhere ahead of the firewall.

In March 2000, Car and Driver took that car and put it against the new V8-engined BMW M5 and the Mercedes-Benz E55 AMG, in a story called Bullet Sedans. The Jaguar finished third of three.

We are not going to relitigate that test, because the two Germans are context here, not opposition. But the numbers are worth putting side by side, because they explain the result completely and they do not embarrass the Jaguar at all.

Bullet Sedans, by the numbers

Every figure here is Car and Driver's own, measured on the same day by the same crew. The Jaguar loses on brakes and grip, matches the Mercedes on speed, and wins the row at the bottom.

Jaguar XJRBMW M5Mercedes-Benz E55 AMG

All figures from Car and Driver, “Bullet Sedans,” March 2000, as supplied to Carveyance from the archive. Bars compare only within their own row. Quarter-mile trap speeds: Jaguar 103 mph, BMW 108, Mercedes 103. Horsepower as printed: Jaguar 370, BMW 400, Mercedes 349. Top speeds: Mercedes 157 mph, BMW 156, Jaguar 154. The M5 was the only one of the three with a manual gearbox — a 6-speed, against two 5-speed automatics. Observed fuel economy: Jaguar 14 mpg, BMW 14, Mercedes 16. 2026 dollar equivalents are Carveyance's own arithmetic.

Read that carefully, because it is not the drubbing third place implies. The Jaguar beat the AMG Mercedes to 60 mph — 5.3 against 5.5 — and then ran an identical quarter mile with it. 13.9 seconds at 103 mph, both cars, same strip, same afternoon. The one with the walnut dashboard and the chrome window frames matched the one with AMG badges on it, while carrying 113 kg (250 lb) more weight.

Where it genuinely lost was in the two rows that have nothing to do with the engine. It took 168 ft to stop from 70 mph against the Mercedes' 161 and the BMW's 156, and it held 0.85 g on the skidpad where both Germans held 0.90. Brakes and grip. Which is exactly the complaint the magazine made in prose about the body moving around under load — the numbers and the notes agree, and that is the honest weakness of this car.

The BMW won, and the reason is not mysterious: 400 horsepower, and the only manual gearbox in the test. Three pedals against two automatics is worth real time on a drag strip and more than that on a mountain road. It was a fair win.

And then the bottom row. The Jaguar was the cheapest car there — $2,263 under the Mercedes and $3,072 under the BMW, which is roughly $4,000 and $6,000 in today's money. It was the prettiest of the three, it had the best interior by a distance, it beat one German to 60 and tied it through the quarter, and it undercut both on price. It finished third on points. It is not remotely obvious that it was the wrong car to buy.

But the losing entry is worth reading closely, because almost everything the magazine complained about has since become the reason people want the car, and almost everything it praised has since become impossible to buy.

“From its fluted hood that echoes its headlamp contours to its crosshatch wire grille and its low and sleek profile, the Jaguar XJR is the looker of the lot. The visual delight continues inside, where sumptuous, fragrant Connolly leather is found alongside more square inches of polished wood trim than either Teutonic competitor offers.”

“Yet despite its traditionally elegant styling and the age of its platform, which debuted in 1986 as the XJ40, this XJR picks them up and puts them down with youthful muscle. It scooted from a standstill to 60 mph in 5.3 seconds and covered the quarter-mile in 13.9 seconds at 103 mph. Furthermore, it stopped from 70 mph in a short 168 feet and displayed 0.85 g of stick on our skidpad. In other words, this car is a 4015-pound rocket.”

Car and Driver, “Bullet Sedans,” March 2000

The complaints were real and fair. The seat sits high relative to the controls and the roof. The switches on the center console are, in the magazine's word, amorphous. The back seat is meaningfully tighter than either German car's. Traction control has to be switched off before you can drive properly. And the suspension, beautifully absorbent up to a very brisk pace, starts moving about once you push past it.

“But when you start pushing this R model as fast as it will go, the car loses some of its aplomb. Suddenly, the fluid compliance of the suspension is insufficient to prevent the body from pitching, rolling, and generally moving around more than we'd like. Although the XJR never comes close to stabbing its driver in the back, driving smoothly becomes imperative when you're trying to make this car hustle.”

Car and Driver, March 2000

Read that again, though, and notice what it actually says. It does not say the car is dangerous. It says the car requires you to be smooth. It says the body moves and tells you it is moving and asks you to work with it rather than around it. In 2000 that was a deficiency, because the benchmark was a car that did not move at all. In 2026, when every fast saloon has been damped into total silence and the steering is a suggestion box, being asked to drive smoothly is the entire product.

The verdict line Car and Driver landed on is the best one-line summary of this car anyone has written, and it happens to be the thesis of this article restated by accident:

Ninth of twenty, in the wet, with the back seats still in it

Here is the number that should reframe the whole car. In December 1997, CAR magazine took twenty performance cars to a damp Castle Combe for its annual handling day. Ferrari F50. A 550 Maranello. An NSX. A Viper GTS. A Skyline GT-R. A Caterham Superlight R that weighed roughly what the Jaguar's doors weighed.

The XJR finished ninth.

Twenty performance cars, one damp afternoon, one stopwatch, and a five-seat leather saloon that finished ninth.

Jaguar XJRFinished ahead of itFinished behind it

Times as published in CAR, December 1997, on the pre-chicane 1.84-mile layout. Sourcing note: this ranked list circulates widely among enthusiasts and matches the cars on sale that autumn, but Carveyance could not verify it against an original copy of the issue. Treat the ordering as reported rather than certified. The Jaguar is an X308 XJR — X300 production had ended that June.

Ninth of twenty, on a damp track, in a five-seat leather-lined saloon with a walnut dashboard and a trunk you could sleep in. It beat a Porsche Boxster. It beat an Integra Type R. It beat a Lotus Elise, which is a car whose entire reason for existing is that it weighs nothing and goes around corners, and which the XJR outweighed by roughly 1,090 kg (2,400 lb).

That result is why the badge is worth anything. Not the straight line — anything with a blower can do a straight line. The XJR went around a wet British circuit faster than most of the sports cars built to do exactly that, while carrying four passengers and their luggage in a room lined with dead cows and dead trees. The rugby shirt at the black-tie dinner, muddy at the knees, holding a drink, perfectly at ease.

One caveat, because Carveyance would rather flag a thing than get letters about it: those ranked times circulate widely among enthusiasts and every car on them was current in late 1997, but we could not put hands on the original issue to check them line by line. Take the ordering as reported. The point survives if a tenth or two moves.

Worth knowing too: late cars could be ordered with the R1 performance package, which brought 18-inch BBS wheels, larger cross-drilled Brembo brakes and retuned suspension. Sources disagree flatly about which years it was available and in which markets, so if a seller tells you their car is an R1, ask for the build sheet rather than taking the badge at face value.

The X350: a revolution disguised as a golf club car park

2003–2009 · 390 horsepower · aluminum · badly misunderstood

In 2003 Jaguar replaced it, and almost nobody noticed what they had done.

The car that arrived looked like the car that left. Slightly larger, slightly more upright, four round headlamps, the same long hood and sloping tail, the same wood and the same leather. To a casual eye it read as a facelift. Andrew Frankel, writing for Hagerty two decades later, described the reaction with a phrase that has stuck to this car permanently and unfairly:

“A slightly more upright version of the previous generation XJ, with a bit more space and quite a lot less grace. Not much to get excited about here. Or so it seemed. In fact the car was a revolution. Because beneath those golf club car park looks lurked what I believe to be the first entirely aluminium monocoque designed for a mass production road car.”

Andrew Frankel, Hagerty UK, September 6, 2022

He hedges, and he is right to. The Honda NSX got to an all-aluminum monocoque first, in 1990, at volumes that make “mass production” do a lot of lifting. Audi's A8 was aluminum before the Jaguar, but the A8 is a cast spaceframe with panels hung on it, a different animal from a monocoque where structure and skin are the same thing. The honest claim is narrower than the headline and still remarkable: the first all-aluminum monocoque built for genuine volume production.

How you glue a Jaguar together

Aluminum does not like being welded the way steel does, so Jaguar borrowed the answer from aircraft: bond it and rivet it. The technique is called riv-bonding and it had never been used in volume car production. Roughly 3,200 self-piercing zinc-coated boron steel rivets and about 110 meters (120 yards) of aerospace-grade epoxy adhesive, laid down by robots and heat-cured. Fifteen castings, thirty-five extrusions, 284 stampings. The outer panels were 6111 alloy, chosen because it bake-hardens — the shell got stronger going through the 170 °C paint oven. It took new robots, presses and curing ovens at Castle Bromwich, and the research came out of Ford's own laboratories, which proved the principle in the early 1990s and then had to work out how to do it four hundred times a day.

The result was a bodyshell about 40 percent lighter and 50 percent stiffer than the steel X308's. And the consequence of that is the single most enjoyable fact about this car.

Bigger everywhere. Lighter anyway.

Change from the steel X308 XJR to the aluminum X350 XJR. Every measure of the car grew except the one Jaguar spent all the money on. It also gained a sixth gear and air springs at all four corners, which do not fit on a percentage scale.

Grew (X350 larger or stronger)Shrank

Dimensions and US curb weights from published manufacturer data via Cars.com and Wikipedia's cited tables; Frankel quotes the X350 as roughly 100 mm longer and 148 mm higher, which does not reconcile exactly with those published figures, so Carveyance has computed the changes from the published numbers. Honesty note: Andrew Frankel puts the X350 XJR at 1,665 kg and the saving at 172 kg, a far bigger gap than the US curb weights show, almost certainly because he is quoting a European unladen weight measured without driver or a full tank. The direction of travel is not in dispute; the size of the win is. Carveyance has used the like-for-like US numbers, which give the smaller and safer figure.

It is longer. It is 134 mm (5.3 inches) taller. It has more power, more torque, more room, more equipment, six gears instead of five and air springs at all four corners. And at 1,791 kg (3,948 lb) against 1,848 kg (4,075 lb), it weighs less than the car it replaced. Frankel puts the saving at 172 kg, which is a bigger claim than the US curb weights support — those numbers are almost certainly measured on different standards, and we have said so on the chart rather than quietly using the flattering one. But the direction is not in dispute. Jaguar built a bigger car, made it lighter in an era when everyone else was doing the opposite, and then styled it so nobody would notice.

“The X350 wasn't just a lot lighter than the X308, its structure was 50 per cent stiffer too, so its handling was even more unlikely than its performance.”

Andrew Frankel, Hagerty UK

What it did with all that

The XJR got the AJ34S: 4.2 liters, still supercharged, 390 horsepower SAE in America and 400 PS in Europe, 399 lb-ft, through a ZF six-speed automatic. Multi-link suspension on four-corner adaptive air springs with self-leveling, managed by CATS — Computer Active Technology Suspension — which adjusted damping in milliseconds without asking the driver's opinion, and which woke itself every 24 hours to level the car while it sat parked. That is either delightful or slightly unsettling, depending on how you feel about your saloon breathing overnight. Drag 0.32. Brembo brakes. 155 mph, limited.

Car and Driver ran one for 40,000 miles, and the long-term wrap-up by Ron Kiino in February 2005 remains the best single piece of evidence for this car, because it did not just test the Jaguar, it tested the Jaguar twice: once new, and again ten months and 40,000 miles later.

“You get a lot of extra stuff for that, but mostly you get enormous and instant power from a 4.2-liter V-8 that is seriously kicked up by an Eaton supercharger capable of forcing 13.1 pounds of boost down the engine's 16 little inlet throats.”

“To keep all this brute force from behaving like The Hulk, Jaguar uses an air suspension that automatically levels the ride and offers excellent body-motion control without having to use stiff spring rates.”

Ron Kiino, Car and Driver, February 1, 2005

Now the numbers, which are the good part.

Read the 0–130 row again. After 40,000 miles of magazine staff abuse, the car reached 130 mph nearly three seconds sooner than when it was new. The only thing that went backward was six feet of braking distance, which is a set of pads and a bad afternoon. That is a car that arrives slightly tight and then loosens into itself, which is exactly what a good cotton shirt does.

The staff logbook is where the affection leaks out. Brock Yates, somewhere out west at a steady 90:

And Robin Warner, rather more concisely:

The magazine's own summary of what the car meant is the sharpest thing anyone wrote about it at the time: “The XJR — the whole XJ line, really — changes Jag's rank within the prestige ladder. It is easy where the Germans are deliberate, feathery where they are stout. Consider it a Lexus LS430 with style and 100 more horsepower.” And, crucially, this: “as our long-term test shows, the XJR is downright cheap to maintain.” Hold onto that one. It is going to matter later.

Instrumented figures from Car and Driver's 40,000-mile long-term test, February 2005.

Horsepower, XJR by XJR

Four saloons wearing the same two letters, plus the modern one for scale. The step that matters is the third: the moment the blower moved from a straight-six to a V8.

US SAE net figures except the XJ40 car (bhp, UK). Jaguar's 2013 heritage release quotes the X300 at 326 bhp against the 321/322 given by most independent references — a DIN/SAE difference, most likely. European X350 literature quotes 400 PS (395 hp); the US figure is 390 hp.

The Super V8, which is the same car lying down

Above the XJR sat the flagship. The Super V8 took the identical supercharged 4.2, put it in the long-wheelbase body and loaded the result with everything Jaguar had. It was not faster — MotorWeek measured 5.4 seconds to 60 and 14.0 in the quarter at 105 mph — six tenths off the XJR by Car and Driver's figures, though MotorWeek was working from a slower XJR baseline of its own and put the gap at half a second: “Drop the J-handle into drive, and the long Super V8 leaps to 60 in a short 5.4-seconds. That's only a half second slower than the XJR.” The point was never the six tenths. The point was that you could have all of the XJR's mechanical package and still be driven by somebody else.

Mike Spinelli drove one for Jalopnik in 2006 and produced the most useful sentence in the whole competitive set:

He also noted the thing everyone notices: “the XJ drives like a much smaller car; one could almost consider it nimble,” despite being longer and wider than its competitors. At 1,815 kg (4,001 lb) the long-wheelbase flagship was still lighter than several rivals a size class down. His reservation is the fair one, and it is the same one people had about the whole car: “It's a good car, and a great value, but it lacks the gee-whiz gadgetry and over-the-top luxury of the German competitors.” True in 2006. In 2026, when the gee-whiz gadgetry of 2006 is a museum of failed touchscreens and dead control units, its absence looks less like a shortfall and more like an escape.

There was also an XJR Portfolio, limited to 100 cars, which added polished wheels, larger exhaust tips, chromed side vents and an aluminum gear lever surround. Australia got five of them. Outside North America the Super V8's role was played by the Daimler Super Eight, with a different grille and boxwood inlays, because of course it was.

The problem nobody at Jaguar could solve

And yet. The X350 was, commercially, the moment Jaguar's reputation for looking backward calcified into a liability. The criticism was universal and it was not about the engineering, which almost nobody understood. It was that the most advanced luxury saloon structure in the world had been dressed as its own grandfather. Cars.com was blunter than any enthusiast magazine dared to be: “While the front end was reassuringly familiar, the new XJ's larger size, and higher stance lacks the lithe look of the older car. From the rear door on back, it resembles a Buick LeSabre.”

Two credible explanations, not mutually exclusive. The first is Ford, which owned Jaguar and was frightened of its own customers; as Curbside Classic puts it, “Ford was worried that a break from tradition would alienate existing buyers, who were fiercely loyal.” The second is sadder. The styling was begun by Geoff Lawson, Jaguar's chief designer, who died suddenly in 1999 at 54, and Frankel's account is that nobody afterward wanted to interfere with what had become the final design of a great man's career. Whether that is the whole truth or a kind story told later, it is the version the people who were there tell.

Jaguar knew. The 2007 X358 facelift tried to fix it with a bigger lower grille, a badge moved into the grille instead of onto the hood, and prominent fake side vents on the front fenders. It fooled nobody. Eóin Doyle of Driven to Write was merciless and correct:

“The revised XJ (dubbed X358) was greeted with gasps of incredulity, largely because it looked so half-hearted and worse still, cheap.”

Eóin Doyle, Driven to Write, May 21, 2020

Craig Cheetham, in 2017, reached the conclusion most people reach eventually — that the car was right and its timing was wrong:

“Like all Jaguar XJs, the X350 offers fantastic ride quality, ironing out bumps like no other car, while maintaining the agility of a much smaller vehicle. Comfort and handling, then, are exemplary, as, indeed, is the luxury of the car's cabin. Indeed, the only real criticism of the X350 is that, in many ways, it was too traditional... but irrespective, the X350 is a wonderful, rewarding and cossetting car.”

Craig Cheetham, Honest John Classics, 2017

Ian Callum went the other way entirely with the X351 in 2009, giving it what he called “a rebellious edge.” But that is a different article. Here is the thing about being unfashionable: it is temporary, and it is inexpensive while it lasts. Peter Burgess got there in 2003, before anyone else:

“The big advantage that this Jaguar offers over and above the Audi A8, BMW 7 Series and Mercedes-Benz S-Class is a sense of individuality. This is a car which stands apart from the competition yet in most ways is their equal. While the Germans are caught in a technological spiral of ever-outdoing each other, the British car gets on with the job of looking after the driver and passenger in a rather charming way.”

Peter Burgess, Motoring Research, 2003

Twenty-three years later, most of those German cars are running electrical horror stories and the Jaguar is the sensible choice. Nobody saw that coming, least of all Jaguar.

Two shirts, one wardrobe

Which is which, and why it matters

So. Back to the laundry.

The X308 is the vintage rugby shirt. Heavy cotton, worn thin at the elbows, the collar gone soft, a stain on it that has a story attached. It was the inception and it was the hot rod, and it is still quick by current standards while very obviously showing its age. The muscular nose, the low roof, the aggressive rear: it screams old-school in a world of designed-by-committee surfacing. People come up to it. They want to hear about it, where you got it, how it fits into a landscape where nothing else looks like that anymore. And that is precisely where it shines — and then you drive it against the things it is parked next to, and the curiosity turns into something closer to respect. Pulling slowly up a gravel drive in the Hamptons it makes that noise, that particular blend of blower whine and V8 restraint, and it announces you before you have opened the door. Leaving, it lays down the tire marks of tradition, as a sign that you are still a player in the game.

The X350 is the refined shirt. Not the heavy cotton: the blend. Easier to breathe in, easier to live with, and considerably harder to get hold of when you are running. In almost every way the X350 XJR and the Super V8 were the pinnacle of old-world Jaguar, and the end of it. Refined, lighter, larger, faster, more luxurious. It might have been better suited to polo than to rugby. And yet at certain angles — mostly the ones you catch in motion, from three-quarters behind, when the light is going — it shows you exactly where it came from and what its lineage is about.

Or, if you prefer the version without the metaphor: one of them is a hot rod with wood in it, and the other is a figure skater who can hold a cup of tea through a double axel without spilling a drop, travel down the Autobahn, a mountain road and a back road without noticing any of them, and conquer the finance world from the back seat while doing it.

You will need a good seamstress

Everything that goes wrong, and roughly what it costs

The rule about old British cars applies here with force: buy the car, then find someone who can sew. These are not fragile machines — the AJ-V8 is documented running past 150,000 miles without drama and Classics World calls it “remarkably robust” — but each generation has one specific, known, expensive thing it does, and the difference between a bargain and a disaster is entirely whether the last owner dealt with it.

X308: two problems, both solvable, both non-negotiable

The timing chain tensioners. This is the one. The early V8s used tensioners with plastic housings, and the plastic goes brittle. The Jaguar Clubs of North America put typical failure at 50,000 to 70,000 miles; RepairPal's owner data across 28 reports averages 85,341 miles, with a range from 35,100 to 133,000. The symptom is a rattle on cold start. The worst case is chain slack letting a piston meet an open exhaust valve, and JCNA puts that bill near $10,000. Metal replacements run roughly $1,400 in the US or about £950 for all four in Britain, and later cars use the 4.2's parts. There is no gambling on this one: if the seller cannot show a receipt for tensioners, budget for tensioners.

Nikasil. The early AJ-V8s used Nikasil-coated bores, a motorsport-proven low-friction lining with one fatal enemy — high-sulfur gasoline, which forms sulfuric acid in the cylinder and eats the coating. The rings then score the bores and compression walks away. The commonly cited changeover is engine number 000818-1043, dated August 18, 2000, after which steel liners were used, and many affected engines were replaced under warranty with the later unit. Treat that number as a guide rather than a guarantee — specialists put the transition anywhere from 1999 to late 2000 and it appears to have been phased rather than clean. What matters is the engine number rather than the model year, and what actually settles it is a compression test.

Also on the list: plastic water pump impellers that disintegrate without warning, and rust around the front bulkhead, suspension mounts and sills. The Mercedes gearbox is the strong part of the car despite being labeled sealed for life, and a seller who has changed the fluid anyway is telling you something good about themselves.

X350: the air is the problem

Air suspension. Everyone's first answer, and correctly. The compressor's Teflon piston ring wears and stops sealing, throwing codes C2302 and C2303; replace the relay at the same time or you will do the job twice. Height sensors drift. The valve block's ports get sticky. A used pump is about £150 ($200), a new strut from Jaguar about £1,000 ($1,340) and a used one £100 to £180 ($134 to $241), and a full coil-spring conversion runs roughly £1,500 ($2,000) if you decide you have had enough of the whole idea. Our advice: do not convert it. The air suspension is most of why this car rides the way it does, and a coil conversion turns a Jaguar into a slightly odd Ford.

Brakes, on the XJR specifically. The Brembo front calipers can stick slightly, cooking the pads, which fades them, warps discs and gives you a steering wobble. Pad knock-back is the other one: disc movement pushes the pads off the centerline and the first press of the pedal feels soft. Neither is dangerous if you know it is coming. Both are expensive if you do not.

Everything else. Control arms last roughly five years and announce their end with knocking and nervousness. Ground contacts behind the headlights fail and cause what Autocar calls electrical havoc. Torque converters go on high-mileage cars. Aluminum panels corrode where they meet steel fasteners, headlight lenses go opaque, door locks and window regulators misbehave. Note that the timing chain issue belongs to the X308 and does not follow into this generation — if a seller raises it about an X350, they are reciting the internet rather than the car.

The part where you find out what they cost

Sit down first

Both of these were six-figure cars in today's money. The X308 XJR was $67,400 in 1998 and a loaded one crossed $70,000, which is roughly $136,000 now. The X350 XJR was $74,995 in 2004, about $131,000 today. The Super V8 was $90,330 in 2005 and the Portfolio $115,995 in 2006 — close to $190,000 in 2026 terms for a Jaguar saloon with rear DVD screens.

The bill, then and now

The entire buying case in one picture. Every one of these was a serious luxury purchase. They are now priced like used commuter appliances.

New prices from Cars.com and Jaguar US literature. 2026 equivalents are Carveyance's own arithmetic using US CPI and should be treated as approximate. Current values are the midpoint of 2025–2026 public sales, not asking prices.

Against the original sticker, a good driver has lost about 85 percent. Against what that sticker is worth today, closer to 92. Even the very best cars in the country sit at roughly half their 1998 or 2004 price before you adjust for anything at all. Classic Motoring's summary of what is left is not hyperbole:

And Andy Enright, writing for the RAC in 2007, got there before the market did: “the Jaguar XJ makes a great used buy. It's reliable, well built and great fun to drive. Here's a British built car that knocks the Germans into a cocked hat.”

Here is what people have actually paid over the last twelve months, at public sales, with the receipts.

What people actually paid, 2025–2026

Every dot is a real result at a public sale. The spread is the story: on both cars, condition and history are worth more than the model year.

Results collected from Classic.com and The Classic Valuer, covering Bring a Trailer, Cars & Bids, Historics, Manor Park and Iconic Auctioneers. Sterling results converted at approximately $1.34 to the pound for comparison only; the pound figure is the real one. Hover any dot for the car.

Look at the shape rather than the individual dots. On the X308, a genuinely low-mileage, late, unmodified car makes $20,000 to $34,000; a sorted 60,000-to-100,000-mile driver makes $8,000 to $12,000; a tired one is nearly free and will cost you a fortune. On the X350 the spread is more violent still — one 2003 car made the equivalent of about $29,200 in July 2026 and another 2003 car made about $7,700 six weeks earlier. Same model. Same year. Nearly four times the money.

Two things follow. First, this market is not priced on model year or specification but on condition and history, which means the buying advice above is not fussiness, it is the entire game. Second, the top is moving. That $33,750 X308 in August 2026 and the £21,375 ($28,600) X358 at Iconic weeks later are not outliers so much as the first of these to be treated as classics rather than as used Jaguars. Frankel called them “enticingly affordable” in 2022 and they have not become less so; they have just started to be noticed. The floor, meanwhile, is doing what floors do at the bottom of a depreciation curve, which is holding still while everything above it rises. There is a window here, and windows close.

So which one

The honest answer, and it depends on what you want to be

Both. That is not a cop-out, it is the finding, and it is why this piece covers two cars instead of one. They are not competitors. They are the same idea at two stages of its life, and which one is right for you comes down to one question: do you want the car to be an event, or do you want it to be a superpower?

Take the X308 if you want the event. The hot rod with the aggressive face and the noise. People will love it. They will sit inside it and genuinely wonder whether they have stepped into a time capsule — whether they are witnessing old-world England, or about to be handed a drink and told a long story about the Cotswolds. This is a cabin from the era when wood was wood, when a car interior wrapped you in romance and elegance and cocooned you in warmth, when leather was coming out of your ears because it was on everything. It moves under you. It asks you to be smooth. It sounds like power, because it is. It is the shirt with the story attached, and it is by some margin the cheaper way in.

Take the X350 if you want the superpower. The larger, more graceful figure skater. This is the car that will do 90 mph across a state line without appearing to work at all, then hold 0.86 g on a skidpad after 40,000 miles of being thrashed by magazine staff, then take four adults to dinner with the air suspension breathing quietly underneath them, and never once tell anybody what it is. It is the most technically advanced car Jaguar built in that era and it is dressed as the least. That gap is the whole joy of it. As Frankel put it, you will be driving “one of the most unlikely and enjoyable Q-cars out there,” and he is right, and almost nobody knows.

Take the Super V8 if you have staff, or intend to pretend you do. Same mechanical package, longer body, better back seat, six tenths slower and entirely unbothered about it.

What both share, and what almost nothing built since shares, is the specific pleasure of not being read correctly. Every fast car sold today announces itself: the vents, the wing, the badge the size of a dinner plate, the exhaust note piped through the stereo. These two announce nothing. A mesh grille. A small badge. Slightly larger pipes. Everything else is a Jaguar saloon a retired accountant might drive to a golf club — which is exactly the joke Frankel was making, except that when you press the throttle the accountant turns out to have been a flanker all along.

That is the rugby shirt. Not the aggression and not the elegance, but the fact that it is honestly and simultaneously both, and that the elegance is not a disguise laid over the aggression — it is structural. Chouinard's collar was not decorative. It stopped the slings cutting his neck. The Jaguar's wood and leather are not softening a hot rod. They are the reason a 4,000-pound saloon with 370 horsepower makes any sense at all as a thing to own, and they are the reason you will still want to sit in it in twenty years, long after the German cars of the same vintage have been broken for parts by their own electrical systems.

Buy one. Have the tensioners done, or the air springs, or both. Find a good seamstress, because you will need one, and because the whole point of a garment worth keeping is that it can be repaired rather than replaced.

And then go and get it dirty. We can only hope the next generation of Jaguar keeps the lineage going and keeps the rugby shirt torn, worn and stained at a sunset meetup somewhere on the European coast, with the collar up, because that is the only condition in which a shirt like this has ever looked properly right.
