What is the difference between SMG I and II? Is there anything to specifically look out for or be worried about?
Looking at a car tomorrow which is specifically advertised as SMG II and I wasn't sure if its different on earlier E46 M3s or something you could spec?
SMG II was the 'box on all E46 SMG cars.
SMG 1 was on the E36. All E46 are SMG 11
