Although having a family resemblance to the XK120 and XK140, the XK150 was radically modernized. A one piece windscreen replaced the split screen and the wing line no longer dropped as much over the doors. The bonnet was widened, opened down to the wings, and on the roadster the bulkhead was moved back four inches to make the bonnet longer. In the interior, the XK140’s walnut dashboard was replaced by one trimmed in leather. On the early drophead coupés, an aluminum centre dash panel with an X pattern engraving was fitted which looked similar to the early 3.8 E-type. It was discontinued after June 1958. Thinner doors gave more interior space. The standard engine, the same as fitted to the XK140, was the 3.4 litre DOHC Jaguar straight six rated at 180bhp at 5750rpm but most cars were fitted with the SE engine that had a modified cylinder head with larger exhaust valves rated at 210bhp at 5500rpm. Twin 1.75-inch SU HD6 carburetors were fitted. Four-wheel Dunlop 12 inch disc brakes appeared for the first time although it was theoretically possible to order a car with drums. Either wire wheels or disc wheels could be specified. Suspension and chassis were very similar to that on the XK140. These were high performance, well appointed sports touring cars and could cope with long distances with alacrity.
First registered in July 1958, this beautiful example has benefitted from exhaustive restoration over an eight year period, which was completed in the early 2000s. The bodywork was undertaken by specialist Contour Autocraft, whilst all trimming and upholstery was performed by MCT (Mic Turley), arguably the foremost UK Jaguar trimmer, using original patterns from Jaguar themselves.
The restoration was finally completed with meticulous attention to detail and aided by past Jaguar Driver’s Club judges. As a result the XK went on to win the JDC Concours d’Elegance in 2000 and 2001, and was also a finalist in the Autoglym competition of 2001. S831029 has also appeared on the Discovery Channels, ‘A Car is Reborn’ television series.
After winning the previously mentioned competitions, a number of sympathetic modifications were carried out to make it more driver-friendly. Power steering, electronic ignition and an electric cooling fan were added as well as highly effective Coopercraft brakes and a modern alternator. In addition, a stainless steel exhaust system has been added with all original parts kept if required. A very rare set luggage and the original and complete tool kit are included.
Possibly one of the finest in the country, this XK150 Roadster represents many thousands of hours of effort as well as a keen eye for performance and style.
