1968 the British sports car manufacturer Marcos released the first version of Mantis, the Mantis XP. A racing car designed for the sportscar-prototype class, it was powered by a mid-mounted BRM-Repco V8. Later changed to a Buick V8 engine. Like earlier Marcos cars it used a plywood monocoque chassis, albeit different from that of the GT. Only one car was made. A full restoration of the XP was completed in 2008. Now based in America, it has visited the UK for the Marcos 50th anniversary celebrations and the Goodwood Festival of speed. (wikipedia)
