Like I said, get the car out the garage, and take some more pics.
I think it looks ok from what I could see, it looks oldschool, I remember my fathers toyota cressida, and the Merc before that both had the chrome wheel arches, and even his Peogeot before that, and it looked good...
What bmw is that by the way???
WHATEVER you decide, JUST DON'T DO THIS!!!!!!!
