The JAGUAR XJ (2003-07) XJ6 4DR SALOON 2.7 TDVI EXECUTIVE AUTO6 is a large, four-door luxury saloon, aimed at buyers wanting comfort and presence rather than a small, low-cost runabout. In the UK used-car market it sits among prestige executive cars, competing with models such as the BMW 7 Series and Mercedes-Benz S-Class. Its diesel engine and automatic gearbox make it well suited to relaxed motorway journeys. Mycarcheck.com has recorded 719 look-ups across 231 different VINs, giving a useful snapshot of interest in this model. Checks show an average private-sale valuation of £4,400 and an average recorded mileage of 108,000 miles. The typical car has had about five previous keepers, so checking its individual history and condition matters. Despite its age, the XJ remains an individual alternative to German rivals. Its graceful styling, quiet ride and roomy cabin suit drivers seeking long-distance comfort and Jaguar character rather than budget motoring.
