Wow! This thread is blowing up! Personally, I went with the CF roof because I did not use my moonroof in previous 330i and 335i. I also think it looks great with the Alpine white. There may be a slight handling advantage, but not one that most of us would notice. The driver is still the best mod you can make to your car!
