To quickly and very cheaply change the look of your car go for an M3 front bumper,German plate, chrome or black grill, clear corner lights, euro fogs, eye brows if theyre your style, trunk lip. I agree that those rims don't seem to flow well with the car. They look like some one wanted to be a gangster/drug dealer but didn't have enough money to buy real bling rims. Black rims are probably better with green. Or tasteful looking chrome rims. My e36 328i looks very unique and different from most. And the changes I made were pretty cheap. the most expensive thing I did was put on an M3 bumper. Here are some before and after pics on my 328i.
