I've got a 1985 BMW 318i, a slowly but surely I'm trying to upgrade/re-do thing a here and there on the car. It's a maroon/dark red and still has the original 15"x7" 18 hole rims and they're starting to really look bad. I was thinking about having them powder coated a polished silver or a rich gold, any suggestions? Would these colors look good on my car? Any opinions will help!
