The JAGUAR XJ (2007-09) XJ 4DR SALOON 4.2 V8 300 SOVEREIGN AUTO6 is a full-size luxury saloon, built for comfort and graceful long-distance travel rather than city-car practicality. In the UK used-car market, it sits among premium executive cars, offering a more distinctive, traditional alternative to German rivals such as the Mercedes-Benz S-Class and BMW 7 Series. The 4.2-litre V8 and automatic gearbox give the Sovereign smooth, effortless performance, while its spacious cabin, leather trim and calm ride suit business travel and longer journeys with passengers. Mycarcheck recorded four look-ups across two VINs; figures are indicative only given the small sample, not market-wide. Checks show an average private-sale valuation of £8,300, 22,000 miles and about one previous keeper, but the sample is small. Elegant styling, quiet comfort and generous equipment set this XJ apart; buyers should check condition and service history and allow for upkeep costs for an ageing luxury saloon.
