The JAGUAR XJ (2007-09) XJ 4DR SALOON LWB 2.7 TDVI 204 SOVEREIGN AUTO6 is a large, luxury four-door saloon, rather than a family hatchback or SUV. Its long-wheelbase body gives rear passengers extra space, placing this high-specification diesel Jaguar among premium executive cars competing with the Mercedes-Benz S-Class, BMW 7 Series and Audi A8. mycarcheck.com has recorded 128 look-ups covering 45 distinct VINs, a useful snapshot of interest in this relatively specialised used model. Checks show an average private-sale valuation of £4,800 and average recorded mileage of 99,000 miles; typical annual mileage is 4,000, with around four previous keepers. The 2.7-litre diesel and automatic gearbox suit long-distance travel, while Sovereign trim and the XJ’s elegant styling appeal to drivers who value comfort and presence. It is best suited to experienced buyers seeking a refined cruiser rather than low-cost motoring; condition and maintenance history deserve attention in an older luxury car.
