Caterham Cars is a British manufacturer of specialist lightweight sports cars established in Caterham, Surrey, with their headquarters in Crawley, Sussex. Their current model, the Caterham 7 (or Seven), originally launched in 1973, is a direct evolution of the Series 3 Lotus Seven designed by Colin Chapman. In the 1990s the company made the Caterham 21, a two-seater soft top alternative to the MGF and Lotus Elise, (which both sold many more units). A track-only car, the SP/300.R, a joint project with Lola was released for customer testing in 2010 and was scheduled for release in 2013. On 27 April 2011, Team Lotus owner Tony Fernandes announced that he had purchased Caterham.
