I have two sets of rims for my 2014 x5. My wife is now telling me I have to get rid of one set. I'm thinking of getting rid of these. They are from the factory, I believe they are style 451's. I called the dealership and they offered me $750 for all four. That's not a good deal right? I'm not sure how else i'd go about selling them on my own, but $750 seems crazy low. Am I wrong?
