CHs are hot. You might look into the BBS LM-R and the RS-GT as well - I especially like the LM-R. I don't know if M-B are still 5x112, but you might also look into HRE M40s (in Mercedes fitment?) if you want to go mega-baller...
i <3 M40's! i'd rock them in a heartbeat if i could find them secondhand for <2k. I'm too much of a cheapass to buy wheels new and I LOVE the concavity you can get with those in a staggered fitment.
I'm also debating on some Volk LE-37's since they're fairly light, and have a simple design. I don't think it'll go with my theme of the car though :\
I also like the HRE 890 series -- those with a step lip would

I'm going to start looking at some bimmer forums to see if i can find a good set of wheels for cheap. I heard the wobble bolts from Raderwerks are pretty money to get the 5x114.3 fitment to work on audi's...
