Originally just a concept to show off Jaguar's all-new engine, the XK120 went on to re-define the company
Quite simply, the XK120 was the sports car that elevated Jaguar into the big time. Introduced at the 1948 Earls Court Motor Show, it featured an all-new twin-overhead camshaft straight six that lived well into the 1980s. And it was fast: the 120mph maximum speed was the reason for its name. Yet the XK120’s real forté was its sheer all-round driving pleasure for such a low price. The earliest aluminium roadsters are easily the most valuable (£225,000-£300,000 for an excellent example), with SEs commanding a premium, and the later Drophead Coupés not far behind.
