Ginetta Cars was founded in 1958 by the four Walklett brothers (Bob, Ivor, Trevers and Douglas) in woodbridge Suffolk.

In 1967 the G15 was launched withan a Hillman Imp engine. This two seater coupé had a glass fibre body bolted to a tube chassis and used Imp rear and Triumph front suspension. Over 800 were made up to 1974 and the car was fully type approved allowing for the first time complete Ginetta cars to be sold. Eight G15s were engineered for Volkswagen engines and called the Super S.
