The Jaguar XK150 S was an extremely rare car even when it was new. It has a 3 carburetor set up instead of the 2, higher compression and a completely different cylinder head. Even by todays standards they are fast. When it came out in 1950's, it was a marvel. We did a mechanical restoration on this one and it gets driven and taken to shows regularly. It is still just as incredible as it was the day it was new.
