Incredible find and interesting car. Not a bit fan of the aftermarket wheels. The bonnet is an improvement and it can handle the stickers. Looks racey!
I think is a " Alfa Romeo SZ 3.2 GTA Trophy Racing "or " wheels race,roll-bar etc .
Yes, I believe it is a an Alfa SZ Trofeo, hence the wheels, and some other details such as the rollcage inside :)
