The GT body style was first introduced in 1964 with a Volvo B18 unit with overdrive gearbox and De Dion rear axle. In 1966 they switched to the Ford Kent “Formula Ford” engine. The plywood chassis was glued together from 386 separate pieces and was not only light and strong. Although most people have never heard of Marcos which ceased production in 2007 you have heard of the drivers who raced them. Among the drivers were Jackie Stewart, Bill Moss, John Sutton, Jack Gates, John Mitchell and Jackie Oliver, as well as Jem Marsh.
