Jaguar XJ6 (1968–1992)

The Jaguar XJ6 was launched in 1968 and immediately set new standards for ride, refinement and value in the luxury saloon class. The twin-cam XK engine, independent suspension on all four corners and standard power steering and brakes made the XJ6 a significant advance over its contemporaries. Three series were produced — the pure Series 1 is the purist choice, the Series 2 offers more refinement, and the long-lived Series 3 with its Pininfarina roofline is perhaps the most practical. The XJ12, powered by the legendary V12 engine, offers effortless performance. Common XJ6 concerns include rust in the rear lower quarters and sills, the notoriously complicated air conditioning system on later cars, and the fuel system on early injection models.

Available body styles: Saloon. Produced from 1968 to 1992.
