G.S. Cars was a British automotive manufacturer active from 1975 to 1980, based in Bristol. The company was known for its distinctive body conversion of the Lotus Europa, which was designed by William Towns. This conversion featured a notably angular design that significantly altered both the front and rear aesthetics of the original Lotus model.

The G.S. Cars conversion was first showcased at the 1975 Earls Court Motor Show, where it was displayed on The Daily Telegraph stand. The unique styling attracted attention, leading to the production of approximately 15 units during the company's brief existence. Despite its limited output, G.S. Cars contributed to the niche market of customized sports cars in the mid-1970s.
