Marcos. Originally built by Jem Marsh, and Frank (i think) Costin. Costin came from an aircraft background, where wood as a structural element is more accepted. Used correctly, it can be as lightand as strong, as steel or aluminum. There are some other Costin designed cars around, including some one offs, and wood plays a big role. (As does his sort of odd looking but very aerodynamic design) I would love to have an old school Marcos...
