I've had mostly black cars for the last 20 years, aside from a silver and dark gray, so white is different for me. I think the power level and stance is fine for a daily driver, so I don't plan on really doing anything else at this point.
So far I have added
BMW black grill
IND black mirror caps
powdercoated the wheels gloss black (by me)
powdercoated the calipers a bright green (me also)
window tint
I just had the following completed at Autoglo, in Tucker GA. They have done a ton of work for me, including 2 full repaints and I think they are the best shop in Georgia.
Roof Gloss black
M Diffuser Gloss black
taillights and reflectors lightly tinted.
