The JAGUAR XJ (2003-07) XJ6 4DR SALOON 3.0 V6 SE AUTO6 is a large, four-door luxury saloon, rather than a family hatchback or SUV. In the UK market, it sits among premium executive cars, offering traditional Jaguar style and comfortable long-distance travel in an automatic petrol model. Mycarcheck.com recorded 1,196 look-ups covering 463 distinct VINs, a substantial sample for this model. Checks show an average private-sale valuation of £2,500 and average recorded mileage of 119,000 miles; average annual mileage is 2,000. The cars checked had about five previous keepers on average, suggesting ownership histories can vary and are worth reviewing carefully. It suits drivers seeking a refined car or relaxed motorway companion, especially those who value space, a smooth V6 and a distinctive alternative to German executive saloons. Its classic-Jaguar character is a draw, though running costs and age-related condition matter. Check service records, mileage and keeper history before buying.
