Alfa Romeo Tipo 33 Stradale
The Alfa Romeo 33 Stradale, first built in 1967, was based on the Autodelta Alfa Romeo Tipo 33 racing car. The car was designed by Franco Scaglione and built by Carrozzeria Marazzi. It made its debut at the 1967 Turin Motorshow. The 33 Stradale is believed to be the first production vehicle to feature dihedral doors, also known as butterfly doors. The 33 Stradale also featured windows which seamlessly curved upward into the 'roof' of the vehicle. The Alfa Romeo 33 Stradale is very rare; Alfa Romeo made only 18 of these cars.
