"Fine, we'll do it ourselves." If this isn't stamped somewhere on the BMW M1, it surely should be. The car was originally conceived as a joint Lamborghini-BMW project that would produce a race car with enough street units to meet homologation rules for Group 4 racing. Trouble was, Lamborghini found itself in financial straits and the fellows up in Munich were thus left to finish the M1 on their own. What resulted was a Giugiaro-designed, mid-engined marvel that ended up being the fastest production car of its time.
