Hello lads, Im new to the board everyone:) and I currently own a 99 323i 4door E46 , and My front my bumper has some minor cracks in it and needs some attention to it, and was curious are all e46 bumpers interchangable amongst each othere, . I was thinking of going with a 330i front bumper, or M3? I appreciate the input. Cheers

interchangable yes from 323i to 330i. but with m3 bumper, you'lll have one major issue. m3 bumper is wider then non-m3. so you either have to bend the sides in (not recommended) or modify the sides (cut and shape). i believe the non-m3 uses the alum carrier with the bumper shocks.
