Solved - NEH 2489: Ghia Porsche Typ 764 Sedan proposal - 1960

[fromwien]

I totally agree with you, 'Wendax'. know the 'Spiegel'-pictures very well. But I am still uncertain in this case, if Porsche 'only' made a 'Studie' (sketch, technical proposal, etc..), called Typ 764, and Ghia then, based on the Porsche-design, the 'Prototyp', shown in the picture (on behalf of Volkswagen).
I followed this assumption, as I didn't find any Porsche-project-number for Ghia's second 4-door-prototype (hatchback) from 1962 by now...
