Marcos was a British sports car manufacturer. The name was a combination of founders Jem Marsh and Frank Costin.
Marcos was founded in Luton, in Bedfordshire, England, in 1959 by Jem Marsh and Frank Costin. Frank Costin had earlier worked on the De Havilland Mosquito fighter-bombers and from there he got the idea to use plywood for the chassis. The company moved to a converted mill in Bradford on Avon, Wiltshire in 1963 and in 1971 to a £125,000 purpose built factory at nearby Westbury.
