Donald, Are you sure its not the same car as this one? Do you have any photos of it? Looking at this picture I can see that it has been altered unprofessionaly in a few ways. The aluminium trim has been shortened leaving a hole exposed, there are messerschmitt engine cover catches fitted, all this tells me that it is a modified car. The other thing that makes no sense is that the shape of the nose tells me it is an early body, the early cars were made so that the axles could fold. My car was made this way, there is still part of the mechanism on the car. Surely, having these big fixed wings would be defeating the purpose, it would not allow the car to go through narrow gaps. Sorry Donald but I'm not convinced that they ever made them like this. I may be wrong, It could have been an experimental prototype.
Could this be the car your father bought in the seventies and has found its way to Italy? I still think it one that someone modified. Perhaps we will never know, a mystery like my Torpedo!
