Perhaps this could be an attempt to copy the car that Pietro Frua realized in 1971 for Verne Von Heidrich with a Porsche 914/6 base and a half-Miura/half-Maserati style; actually I suppose that rear lights are not Alfa, but Maserati Khamsin's ones. ...a better look suggests me that also those ones are slightly different, perhaps Fiat Dino coupe'?
