Description

This Jaguar XK-150S Roadster is a very important model in Jaguar’s history, and represents one of the marque’s most desirable post-war British sports cars. This 150S was a rust-free limited ownership example that underwent a documented, concours-level restoration performed to the highest standards by our team. The result is a show-quality Roadster that will appeal to the most discerning Jaguar enthusiast or collector.

This XK-150S has an impressive provenance, with limited ownership history and long-term care by a dedicated Jaguar collector. During its life it was also raced, and today it is accompanied by period programs and a very thick binder of documentation chronicling its journey from new through restoration. It retains many original components, including its head, 4-speed with overdrive, triple SU carburetors, dual fuel pumps, filter box, voltage regulator, and more, as it left the factory. The Heritage Certificate of Authenticity further verifies its original color combination.

Distinguishing it from the standard XK-150, the coveted ‘S’ model featured a higher-output engine with triple SU carburetors, dual exhaust, and superior performance making it the ultimate evolution of Jaguar’s XK line and the most desirable choice for collectors and enthusiasts alike. In 1961, the XK-150 S’s original owner further enhanced performance by having an unstamped 3.8 block installed by the dealership, while retaining the original cylinder head. This period modification is documented in its history and adds another layer of interest to its already impressive provenance.

Included in the restoration process of this XK-150 S: it was stripped to bare metal, placed on a rotisserie, metal finished, leaded, prepared for primer, sealer, paint, base, clear, and was color sanded and buffed to the fabulous finish that you see today. All body parts were fitted to the car in our assembly area. The cabin of the roadster received a completely new custom tailored and fit Tan interior in all the correct materials by our master trimmer. All of the Jaguar’s mechanical systems were completely gone through and were restored or replaced as needed, including: the fuel, electrical, cooling, and hydraulic systems. Mechanical components were rebuilt, including the engine, transmission, rear end, and suspension, and were installed to the 150 S in our assembly area.

With its documented restoration, exceptional fit and finish, and rare specification, this XK-150S Roadster now stands as a concours-level show car, an outstanding piece of Jaguar history, and a superb choice for the most discerning of tastes. Whether destined for the show field or spirited touring, this XK-150S offers its next owner the chance to enjoy one of Jaguar’s most significant models in exceptional restored form!

History

In 1957 Jaguar introduced the XK-150, a replacement for the XK-140. The XK-150 had many similarities to its predecessors but it featured modern styling and improved mechanics. Only 4,450 Coupes were produced of the XK-150 between 1957 and 1961 with 10,000 XK-150’s produced total. The XK-150 was plusher and more civilized, and substantially restyled, with a re-contoured beltline, wider grille and a one-piece windshield. The curvature of the line from front to rear fender was much straightened, resulting in a heavier look. For better drivability, disc brakes were fitted with servo assist. Compared with the XK 140, the following technological improvements can be noted: the XK 150 was fitted with disc brakes on the front wheels and with more powerful engines. The 3.4-litre XK engine fetched a standard 210 hp, and the SE Special Equipment version even 250 hp. From 1958, the XK 150 was also available with a 3.8-litre XK engine with a capacity of no less than 265 hp.
