Having driven BMW's for 39 years I can attest that this V10 is the state of the art in performance in a thoughtful, safe and understated sports car. It's like will not be seen again. I have had two of these - the E39 and the E60.
Acceleration, in town driving with SMG is on a par with a trip to the track and much misunderstood. Only drive this car in SMG and M Mode.
