Previously unseen photo of Franz Weis' 1971 F5000 car. Built from a 1966 experimental GM Indy car chassis, the car was constructed by Weis and Chaparral employees in the Chaparral shop. Aside from the basic chassis, the car was from the mind of Weis. It was raced twice and damaged in its last race. It still exists, bent and unrestored. A Michael Schmidt photo.
