I would just go with some steelies. You can usually find a nice set of older Mercedes rims on ebay or buy a set of those fake Brabus/AMG/Carlson ones. I mean hey, for a couple hundred you dont have much to lose. if they last 5 years then they were worth it I will post some links in a bit.
Ok here are some they are all on ebay:
