I'll refer to a quote I said on this subject before I got into cars:

"Putting aftermarket rims on a BMW (for looks alone) is just stupid, they already have some nice rims that come stock that even look like half the good looking rims one can put on the car anyways!"

However with the stuff listed here, I am reminded and come to the conclusion that anything german looks that much better with anything multispoke. There arent many rims you can put on there that wont look good (sans spinnaz, overly large/100% tasteless rims, etc.)
