I was wondering if anybody can tell me which stock wheels came with an '04 SL500. I currently have the 5 spoke star with the indentation in the middle of each spoke. I am looking at a turbine type look wheel which looks like it has round open circles inside the turbine design (also Mercedes). Was this wheel stock on some '04's or is it an option wheel, or is it an AMG or SL55 wheel? I got a good price on a set and am trying to make a decision very soon. Thanks for any input!
