Arriving in 1957, the XK 150 would be the final incarnation of Jaguar’s XK series of sports cars. As its name suggests, the new model was a progressive development of the XK 120 and XK 140, although it retained the same basic chassis, 3.4-liter engine, and four-speed Moss transmission of its predecessors. The newer model benefited from a new, wider body that provided increased interior space and improved visibility courtesy of a single-piece wrap-around windscreen.

Cleverly, the new body used many XK 120/140 pressings, the increased width being achieved by means of a 4-inch-wide central fillet. At 210 brake horsepower, the standard 3.4-liter engine’s maximum power output was identical to that of the XK 140, but the new model’s main talking point was its Dunlop disc brakes. Fade following repeated stops from high speed had been a problem of the earlier, drum-braked cars, but now the XK had stopping power to match its prodigious straight-line speed.

Completed in February 1958, the Jaguar XK 150 3.4 Fixed Head Coupe presented here was originally finished in Sherwood Green over a Suede Green interior. It is a matching-numbers engine, cylinder head, and body example fitted with the potent 3.4-liter six-cylinder engine and twin SU carburetors. The car was treated to a primarily cosmetic restoration around 2009 that included a complete body restoration and comprehensive repaint (in a lighter color reminiscent of Jaguar’s Willow Green) by the Jaguar experts at Classic Showcase. The brightwork was re-chromed or polished as needed. All new suspension bushings and A-arms were installed, as were new brake calipers and hoses.

Purchased by the current owner in 2010 from Everybody Loves Raymond actor Brad Garrett, the Jaguar has since been improved by the installation of a five-speed gearbox. A collection of invoices from this period of ownership further illustrates the mechanical work performed on the car to ensure roadworthiness. The most recent document dated to November 2023 notes a clutch master cylinder replacement, carburetor jet assembly replacement, and the filling of fresh fluids. In addition, its four-speed gearbox accompanies the sale, along with a service handbook.

A handsome example of a timeless classic with an eye-catching exterior color, this XK 150 is not an example to pass by.
