rear apron - best mod yet!!

My car should be in by the end of the month.
I will be tinting the windows with 20% all around (live in FL so we can do that).
I am also thinking of having the headlight sprayer painted white so it blends into the bumper better (especially since this year it comes with white trim).
I have thought about aero kits and rims. I haven't seen any good pictures of white with an aero kit and white trim (many of you have posted photos with black trim). So I may forget the aero kit.
A spoiler would probably cheapen it too much.
I have the optional parallel rims. I have never owned a BMW before. Is it obnoxious to chrome them? How about polish? I am in FL so they will hold up well.
I am trying to make the car look younger as I am in my early thirties and most of the people who drive them down here are in their fifties.

Thanks for all of your help and advice,
Rod
