This is the finest car I have ever driven. I love the acceleration and handling in addition to the superior comfort of the ride. I can honestly say that I will probably never drive another make other than BMW. I am sold for life on BMW's! the other day, I had a guilty pleasure when I beat a car-full of teenagers in a drag race on the highway. They were amazed!
Climate control, the engine performance and acceleration, the adjustable and heated seats, the sound system.
The only improvement I have to is move the CD changer from the trunk to the dash, possibly behind the dash where the casette player is located.
