In 1972 Opel presented the OSV40 Opel Safety Vehicle Prototype. Based on the 4-door version of the Kadett C, it looked rather bland. The ride height of the OSV40 has been changed. I also made some changes to the body panels and added a front air dam. While working on it I thought I might as well change the body itself. Voilá – the Coupé and Aero versions of the Opel Safety Vehicle.
