I'm sorry to say that I have the same colour combo and I think everything you've done to the car makes it look worse than factory. Starting with the black wheels, which make the car look like it is all wheel well and no wheel (i.e. white to black contrast) and in my view the cars looks worse and worse as you keep lowering it. I haven't seen a vinyl roof since the 1980's Chrysler Cordoba (with "rich Corinthian Leather") and all the money after that seems to make the car look like it belongs on a gang block somewhere.
If it was my money, I'd have just taken what you've spent plus the cost of your car and bought a 2014 M5 with the competition package. Classy understated looks with killer performance.
That's just one man's opinion though. You posted so I thought I'd provide feedback.
Enjoy though!
