Solved: Allemano's № 785 - 1963-1969 Dättwyler Porsche Poroto Spezial

Looks like a Porsche 904 replica, probably based on a VW Beetle?

It was intended to look like a Porsche 904, but it's not VW-based.

It's a Porsche 356 SC built by Otto Dättwyler, and the car is named "Porotto"

But I'm afraid it's a repost since I found the above information through Google on ... autopuzzles.com!

You're right, thanks.
That's because I had the spellilng as 'Poroto' and the builder's name with only one 't'...  then it doesn't show up on a search.
I also searched for 'Peter' and 'Porsche Special' (as I had the builder as Otto's son Peter, but maybe that's wrong).
Anycase since it's quite a recent puzzle I'm going to have to merge it without points; sorry.
