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).
