My dealer told me that if the wheel part number on the new 3 Series matches the ones on the new 2-Series, the backspacing (ET) and of course bolt pattern will match. All this to day, to shop for new wheels on TireRack or similar would merely be a search for 3-Series compatible wheels.

I'm still not comfortable buying new wheels yet, though. Everything rests on that ET and how it relates to the fender! If one is particular, it's a nervous process sometimes to spend that money sight unseen.
