Although the SS came close to series production, both cars ended up as concepts only, tied to the fortunes of the Corvair, which fell after the vehicle had been declared unsafe by pioneering consumer advocate Ralph Nader. As far as the Corvair Monza GT got was Disneyland, where it was used as the basis for the World of Tomorrow car ride attraction. Today, the Corvair Monza GT concept car is one of the more than 700 vehicles found in the GM Heritage Collection of historically significant vehicles.
