JAGUAR XK150 Roadster
The Roadster differs from previous such XKs in having wind-up windows, though the hood is still quite rudimentary compared with the Drophead’s. There’s also a significant difference between these and other XK150s: the deletion of rear seats allowed the cockpit to be moved back four inches, so the Roadster has a correspondingly longer bonnet. Most came with 3.4-litre engines, but the 3.8 was added in 1959. Both had ‘S’ performance versions with an extra carburettor among other things. Add 12% for 3.4S prices and 30% for a 3.8S.
