Jaguar XJ: the series that carried the company (1968–2009)

From 1968 to 2009 the Jaguar XJ was less a model in Jaguar’s range than the range itself. Launched as the saloon that replaced the company’s entire line-up in one stroke, it stayed the flagship for four decades, and its classic generations now span everything from £3,000 usable elegance to six-figure coupes. This page is the map of the family; our XJ6 guide goes deep on the defining branch.

1968: one car replaces five

By the late 1960s Jaguar built five different saloons; Sir William Lyons replaced them all with one. The XJ6 of 1968 paired the proven XK straight-six with a new shell whose proportions remain the house style half a century later, and its blend of ride, silence and handling led period road testers to call it, flatly, the best saloon car in the world. Nothing at three times the price did so much so gracefully. Demand outran supply for years, and the XJ6 page tells that first chapter’s story in full.

Series 1, 2 and 3: decoding the classics

The classic XJ splits into three series. Series 1 (1968–73) is the original: low grille, slim bumpers, the purest Lyons line. Series 2 (1973–79) raised the bumpers for American regulation and had its quality years under British Leyland, which the survivors have long outlived. Series 3 (1979–92) brought a subtle Pininfarina roof, better build and the longest run, its V12 version outlasting everything. Long-wheelbase shells, Daimler badges and the Sovereign trim thread through all three. Values currently favour honest Series 1s and the best late Series 3s, with Series 2 the value pick.

The coupe and the twelve

Two branches give the family its glamour. The XJ-C of 1975–78, a pillarless two-door on the short wheelbase, is one of the prettiest shapes Coventry ever released and the family’s collector blue chip, in six-cylinder or V12 form. And the XJ12, the world’s only mass-made twelve-cylinder saloon at its 1972 launch, remains the smoothest way the company ever moved five people. The two combined in the Broadspeed XJ12C racers of 1976–77, Leyland’s heroic, heartbreaking touring-car campaign, whose cars are treasured survivors of the era.

XJ40 to X308: the modern classics

The 1986 XJ40, a decade in development, modernised the formula with the AJ6 engine and square-lamp styling that divided loyalists and has since aged into respect; it is today’s affordable entry. The X300 of 1994 returned curves and brought the storming supercharged XJR; the X308 of 1997 added the V8 engines that carried the shape to 2003. All now qualify as classics in spirit and increasingly in status. The aluminium XJs that followed belong to the modern era, beyond this site’s classic scope.

Daimler, Sovereign and the badge ladder

Every XJ generation carried a parallel ladder of plusher badges. Daimler versions, the Sovereign on six cylinders and the Double-Six on twelve, added the fluted grille and richer trim for buyers who found a Jaguar badge slightly loud; from 1983 Jaguar took the Sovereign name for its own top trim, and Daimler moved further upmarket still. The pattern matters when buying, because the Daimler and Sovereign cars were disproportionately garaged, serviced and cherished, and the survivor pool tilts heavily their way. Like-for-like they trade at similar money to equivalent Jaguars, which makes the better-kept badge the quiet bargain of the family.

Which XJ, for whom

The honest matching: Series 3 XJ6 or XJ40 for the buyer who wants to actually use a classic Jaguar weekly; Series 1 for the collector and the purist; XJ-C for the stylist prepared to hunt and pay; XJ12 or Double-Six for the smoothness connoisseur with fuel budget to match; X300 XJR for performance per pound. Across all of them the same three rules apply: structure before specification, history before shine, and the best car affordable over the cheapest available. The XJ6 page carries the detailed buying checks for the six-cylinder core.

On money, the family sorts itself by badge rather than by age: the trim-level cars and the XJ40 are the cheapest big Jaguars anywhere, the XJ6 and XJ8 saloons sit close together in the middle, the XJ12 and the supercharged XJR above them, and the XJ-C coupe apart from all of it at around three times a saloon. The full record, 1,818 recorded sales from 1968 to 2009 with what each badge makes and why the family has given back its 2022 gains, is on the page covering what a classic XJ sells for.

The XJ’s place

No other British car held its maker’s flagship post for forty years, and few shapes anywhere have been evolved so patiently for so long. Over 800,000 were built across the classic generations, prime ministers and royalty rode in the long-wheelbase cars, and the silhouette became shorthand for a certain kind of British arrival. The Jaguar XJ series is the through-line of the company’s modern history, from Lyons’s masterpiece to the V8 era, and its classic generations offer more car per pound than almost anything in the 1970s and 1980s catalogue. Start with the XJ6 guide; the family rewards the tour, and the right car from any of its four decades still does what Lyons intended: makes every arrival an occasion.
