Hey, If I bought an M3 in Europe and had it shipped to the US, what processes do I have to go through to make the car legal for road use here? I already know that 90 and up models will need airbags, so that is out of the question. What if I import an 87-89? Will it need USDM bumpers or anything of that sort? All info greatly appreciated, as my search hasn't come up with much good info.
