The Jaguar C-Type (also called the Jaguar XK120-C) is a racing sports car built by Jaguar and sold from 1951 to 1953. The "C" stands for "competition". The car used the XK 120 running gear in a lightweight tubular frame designed by Jaguar Chief Engineer William Heynes with an aerodynamic aluminium body jointly developed by William Heynes, R J (Bob) Knight and later Malcolm Sayer. A total of 53 C-Types were built, 10 for factory racing and 43 of which were sold to private owners mainly in the US.  Because of the rarity of these vehicles a number of replicas can be found in the market.
