By the time the XK150 was launched in May 1957, Jaguar had already secured four Le Mans victories and was on the cusp of a fifth. A natural evolution of the XK140, the newcomer featured subtly revised bodywork, a more spacious interior and, most notably, disc brakes all round – a first for a production Jaguar. Available in Fixed Head Coupé and Drophead Coupé forms from launch, the Open Two-Seater Roadster joined the range in 1958, with just 2,672 Drophead Coupés ultimately produced.

This particularly interesting 1958 XK150 3.4 Drophead Coupé is believed to be the 30th right-hand-drive example produced and boasts some fascinating early history, having been exported to RAF Victorville, California by two RAF Flight Lieutenants before returning to British shores in 1964. It has subsequently enjoyed enthusiastic ownership, with its most recent custodian having cherished and regularly maintained the car for some 24 years. During this time, the gearbox has been rebuilt and a new hood fitted at a cost of approximately £7,000. More recently, in preparation for its next chapter of enthusiastic use, the XK has undergone a programme of recommissioning, with circa £1,500 spent on maintenance and the fitting of the correct 16-inch wire wheels. It has also recently returned from some minor fettling to the doors and boot, while attention has been paid to the braking system. Importantly, the car is structurally very sound, with the doors opening and closing well – something particularly worthy of mention to those familiar with the XK150. We have personally covered some 50 miles in the car and found it to drive well, with a strong-running engine maintaining good oil pressure and operating temperature. It is an appealingly patinated example that could be enjoyed just as it stands, although the cosmetics offer scope for further improvement, including some refinement to the paintwork and interior detailing. Accompanied by a truly impressive history file, Jaguar Daimler Heritage Trust Certificate and current Swansea V5C, this is an engaging and well-documented example of Jaguar’s celebrated sporting Drophead.
