It is clear that this car is derived from a Porsche 356, what is not clear however concerns the rest of the car.
Obviously it is not clear to us for various reasons: the first is certainly our ignorance on the matter; it is impossible for a human being, although enthusiast, to know the history of every classic car ever produced (actually it is nearly impossible to find someone who knows everything about a single brand). The second main reason is that the description does not enter much into the history of this car which is said to be (once) equipped with a Fuhrmann four-cam engine.
Actually there are some photos that take up articles written on this car, whose body was built by the Borghi workshop in Argentina, certainly on the chassis of a Porsche 356, but we have not understood how Abarth is involved, unless speak only of the similarity between this car and the Abarth-Porsche 356 Carrera GTL built in 1960 and 1961.
