I am looking at getting some wheels for my wife's car and wanted to see what people thought were the best size for an '06 325i sedan. I looked at at set of 20inch wheels but I am not sure how they will look. Does anyone have pictures of their cars with aftermarket wheels, 18'' and up? I am still not sold on any particular style yet but I am leaning towards black wheels, possibly w/ a chrome lip. Any suggestions?
