This includes stuff like wiper motor and heater blower. One exception are that the coupe has vented brake rotors where the Bavaria has solid rotors, so you can't swap rotors or calipers. There are some other things different too: rear suspension, gas tanks, maybe driveshaft. All the big stuff swaps tho: engine, trans, diff, radiator, etc. For body or interior, there is much less. Front grills and toolkit swap.
