John Greenwood from Detroit MI burst on the scene snatching the SCCA AP national championship from the Owens Corning team at the 1971 runoffs at Road Atlanta.  He went on to FIA and IMSA endurance racing getting sponsorship from BFG radial tires.  This coupe was restored for Chuck Ungurean, a collector from OH.  It has since been sold.  More info
