your going to get mostly biased opinions, but ill go ahead and give you mine.
so of the 4 color options: red -- usually pretty nice looking, but downside is in sunlight it often looks orange and it grabs attention, metro grey -- sometimes this color looks great, but other times it looks very bland, the white -- i am not necessarily opposed to, I just seemed sort of feminent to me although I must say I love the way it looks with bronze wheels. finally for black mica (the color I've got) its not the easiest to keep lookin clean, I will admit that although this color looks great all the time imo, its very classy and won't grab too much attention, it isn't just a flat black so there is a slight glisten which I think looks very good.
I am not a big fan of washing cars all the time (too busy for that), but for me black was the only color that looked good all the time, so I hada go with that..
given your wheels I think that the white or black would both look great. white and black cars are not the easiest to keep clean. with the black, I like how it works well with the dark interior...
