About the Jaguar XJ6 Series 1
Launched in 1968, the Series 1 XJ6 was the final model designed under the direct supervision of Jaguar founder Sir William Lyons. It replaced four separate saloon ranges with a single, masterfully engineered platform that set new global benchmarks for ride quality and refinement. The 4.2-litre XK engine provided effortless performance, while the sophisticated independent rear suspension ensured handling that rivalled contemporary sports cars. Today, the Series 1 is prized by collectors for its 'pure' aesthetic, featuring the original slim chrome bumpers and a classic dashboard layout that was simplified in later generations.

Jaguar XJ6 Series 1 fun facts
- The XJ6 features twin fuel tanks with separate lockable filler caps on each rear wing, a design quirk inherited from the Jaguar Mark X.
- Sir William Lyons personally drove a 1968 4.2-litre Series 1 (registration PHP 42G) as his daily transport for several years.
- At its launch, the XJ6 was so highly regarded that used examples were frequently sold for more than the list price of a new one due to massive waiting lists.
