The JAGUAR XJ (2007-09) is a large, premium saloon, built for comfort and long-distance travel rather than city-car practicality. In the UK used-car market, it offers a more distinctive alternative to executive favourites such as the BMW 7 Series and Mercedes-Benz S-Class, with classic Jaguar styling and a refined, spacious cabin. Mycarcheck.com recorded 977 checks across 391 different VINs, giving a useful snapshot of cars being considered. The average private-sale valuation is £4,900, while the average recorded mileage is 111,000 miles and annual mileage is 3,000. Cars have had an average of 4.4 previous keepers, so check service and ownership history carefully. This Jaguar suits buyers wanting comfort for business trips, motorway journeys and weekends, rather than a low-cost runabout. Its space, smooth ride and understated prestige distinguish it from mainstream saloons, though running costs can be higher. At this age, a careful inspection and full history are especially important.
