SL Wheels, MAHLE

[Leewolf]

I recently got a 1980 500 SLC Euro. It had a set of MAHLE wheels. These are aluminum and made to look like spokes. They are 15 inch by 7 in. MAHLE is a large german aftermarket engine parts manufacturer. They do not appear to any longer be in the "wheels" business. I am trying to find out three things:
1. Is there any market for these wheels
2. Can these aluminum wheels be chromed. and what might be an approximate cost.
3. Can the wheels be "bead" blasted to a chrome like finish and at what approximate cost.
Any help would be appreciated. Thanks, Lee
