About the Jaguar XJ6 Series 3
The Series 3 represents the final and most refined evolution of the original Jaguar XJ silhouette, featuring a subtle but effective restyle by Pininfarina that increased glass area and modernised the roofline. Under the bonnet, the 4.2-litre XK engine gained Bosch L-Jetronic fuel injection, significantly improving reliability and cold-start performance over earlier carburetted models. It is widely regarded by collectors as the most usable classic XJ, offering a peerless ride quality that remains impressive even by modern standards. While the V12 offered more prestige, the 4.2-litre straight-six is the enthusiast's choice for its balance of performance and easier maintenance.

Jaguar XJ6 Series 3 fun facts
- The Series 3 was the first Jaguar XJ to offer a factory sunroof and cruise control, reflecting its move toward modern luxury standards.
- Despite the launch of the all-new XJ40 in 1986, the Series 3 V12 remained in production until 1992 because the new car's engine bay was too narrow to fit the V12 engine.
- The Series 3 was the last Jaguar saloon to be designed with direct input from company founder Sir William Lyons before his retirement.
