Westfield Sportscars are manufacturers of both factory built and kit versions of several two-seater, open top sportscars. Their main product line is a Lotus Seven inspired car - vehicles originally designed by Colin Chapman with only the bare essentials for motoring in order to give the rawest and most exhilarating driving experience in the words of Colin Chapman "Less is more".
Whilst Caterham Cars bought the rights from Lotus Cars, Chris Smith set up a rival company and manufactured kits with very similar styling and construction. This led Caterham to threaten litigation (based on Industrial design rights) in the late 1980s which was eventually settled out of court and resulted in Westfield improving and changing the design of their cars. Westfield and Caterham cars are somewhat different in construction. Westfield prefers to employ the same glass fibre body method that Lotus has traditionally used for their other models such as the Elise, Esprit, and Elan, rather than the aluminium used by Caterham.
