Would anyone know where i can get one of these from please? Recently had mine knocked off. I understand they are expensive so was hoping to even use the internals from the existing one to put into a new one, i think the motor is fine however will need a glass.
E-bay is probably the best chance you have of a reasonable price, but you will end up with a pair. Try a few BMW breakers (again you will have to buy them as a pair).
