This car is powerful and fun with only 400 hp, but after you break it in and let loose all 507 hp, it is a beast. While the SMG is new and initially awkward at first, I now have fallen in love with the paddle shifting method and wish all my cars had it.
I think the HUD is great for situational awareness. The voice control iDrive system is wonderful. iDrive is great unless you are one of those who are afraid of computers... I love it!
Better gas mileage, but with the huge demand for fuel with this powerplant, it's not much of a complaint. What kind of mileage do you expect for 507 horses? Pirelli P Zero Corsa's instead of the Continentals... Lose the amber turn signals and go for clear ones. Higher quality paint.
