Should be a modular car that can be converted from roadster to shooting brake pretty much like a Nissan Pulsar EXA.
And coupe, but absolutely that is correct, very well done!
The text accompanying these images:
This idea for different combinations of basic panel and structural elements to produce a range of vehicles at minimum tooling cost comes from Werner Bührer, a 25-year old Swiss student body designer working in Stuttgart. The basic model is a two-seater sports car which can be changed into a convertible or a hard top coupe, retaining the same panels below the waistline. Suggestions are also made for producing an occasional four-seater station wagon by removing the rear deck and fitting a different roof and for a Gran Tusimo coupe with four seats.
The sketches, worked in perspective, show a good feeling for line and balance of masses, although the basic idea is not entirely new. Apparently the intention in this scheme is that the owner should have a stock of sufficient different parts to provide him with a range of body types to suit all his motoring needs. With garage space often impossible to find, the question arises where he would store the parts not in use. The scheme would certainly fail unless sufficient rigidity could be obtained to prevent leaks and rattles.
'Sports car with interchangeable body sections' is as close as this comes to receiving an official name.
