 My M3 is Imola Red with the Red/Black interior. It has all options including the nav system and SMG II sequential manual gearbox which is great! The "automatic" mode is a godsend in stop and go traffic. I didn't buy this car for fuel efficiency, which is a good thing. The best I've averaged on the hwy was about 21...and I've already seen some 15 mpg "in town" tanks.  As such, the 16.5 gallon tank empties FAR too quickly, with fill ups as often as 250 miles.
