The JAGUAR XJ (2003-07) XJ6 4DR SALOON 3.0 V6 EXECUTIVE AUTO6 is a large, four-door luxury saloon, aimed at buyers seeking comfort and presence rather than a small, economical runabout. In the UK used-car market, it sits among traditional executive cars, offering a distinctive alternative to German premium saloons today. mycarcheck.com has recorded 39 checks covering 17 distinct VINs for this model, with an average private-sale valuation of £3,200. The checked cars averaged 106,000 miles, about 3,000 miles annually, and roughly four previous keepers. These figures offer a snapshot, not a guarantee of every car’s value, history or condition. Best suited to drivers wanting long-distance comfort, passenger space and a cabin with an upmarket feel, the XJ is less appealing to budgets or buyers prioritising low fuel bills. Its smooth V6 automatic, Jaguar styling and comfortable ride give it more character than many German rivals; condition checks matter when buying used.
