The British-built Caterham clubman sports car evolved from the original Lotus Seven in the early 1970s. Over the years it has been developed and improved while staying true to the original design philosophy of more performance with less weight. The Melbourne-based company Caterham Cars Australia imports a range of models designed for use on the road and the track. It sells them through their Melbourne outlet, but has service agents in major centres around the country. The range includes the Seven 275, the more comfort focused Seven CSR, and the ultimate 485.
