Launched in 1958, the XK150 S represents the ultimate development of Jaguar’s legendary line of XK sports cars. In its original 3.4-litre form, the “S” model yielded significant performance dividends, with three SU carburetors, straight-port intake manifolds, and upgraded camshafts contributing 60 hp over the standard XK150. Equipped with Le Mans-proven Dunlop disc brakes, these Jaguars were among the fastest and most comfortable GT cars of the late 1950s. The most sporting version was the Roadster, of which only 888 were built.

This open two-seater was dispatched to Jaguar Cars New York in precisely the form that we see the car today, according to its Jaguar Daimler Heritage Trust (JDHT) Certificate. It has 3.4 “S” specifications, with the addition of the practical Laycock de Normanville electric overdrive (suffix DN) and is further finished in black with a red interior and black top.

Having acquired a Jaguar XK140, Mitchell Rasansky’s search for that model piqued interest in its successor, the XK150. When he discovered this example near the completion of its restoration, it proved irresistible. When finished, its transaction was completed and the car arrived in Texas.

Never toured or shown by Mr. Rasansky, the Jaguar remains in extremely good aesthetic order, and should prove to be a popular show car.
