Okay, Sorry Jaray and Allemano, you guys are completely right. As i said, i wrote an article about the mystery of this car and as soon as this puzzle was solved, i wanted to check if this was really an Abarth. I shouldn't have posted the event, but didn't realise it was a serious part of the puzzle. I thought we were all interested in the origins of cars, not the context of a specific picture. Sorry for that.
BTW: Before this puzzle I didn't even know google images existed...
@Paul Jaray: I found the car in a 1966 french car magazine, i think it was called "L'autojournal".
Three cars were running through the streets of Liechtenstein.
The dashboard looks very Lombardi Grand-Prix...
I'll keep you posted about the article around this car.
