39. 1948 Jaguar XK120
It might be hard to believe, but Jaguar actually shied away from producing sports cars from 1940-1948 – the events of the Second World War didn’t exactly invite a big market for sports cars in England and war-ravaged Western Europe. It debuted at the 1948 London Motor Show as a show car for the new Jaguar XK engine, but caused such a stir that Jaguar founder William Lyons ordered it into production. The very first one to roll off the production line in 1949 was delivered to American acting legend Clark Gable.
