Aftermarket wheels roughly equiv to SLK32 stocks?

It's time to replace my tires on my 01 320 and the wheels are kind of beaten up. Was thinking of going for a wheel/tire package, maybe going for the 17" size on the stock SLK32. Want to get a bit sportier look and feel, not going to try to push the envelope too much. Not taking it to the track, but do like the feel on the highway and in the mountains.

Any suggestions for wheel/tire packages? I've had luck with snow tires/rims from tirerack, but going for nice lightweight non-MB rims I'd like some second opinions...

Thanks!
