Apal Buggy - sunroof
The beach buggy based on the Volkswagen Beetle got a sunroof instead of a complete top. The Schroth-Belts are fastened to the roll-over bar and so the base results wrinkles.
Amongst others this type of car (also from Maplex etc.) is known from the movie "Watch out, we're mad!" ("… altrimenti ci arrabbiamo!" 1974) with Bud Spencer and Terence Hill.
