Why didn't you tell your friend with the 750LI something about tuning cars. I mean BEFORE it was too late. the white one is great (should maybe lower it a little at the front), way better than the rolling disco of your friend.
Wow, this rim´s are fitting very well on your sedan, good taste. Just the wood trim´s in the car are not my taste, it make the dashboard old, like a car from England.
