Just got done driving 4000 miles across country. All I can say is that I'm very disappointed. Engine is fantastic, and the suspension is good, if not a touch soft. Fuel economy is decent, and pretty much what I expected. The seats are pretty comfortable and supportive on long trips, though not the best I've been in. What I didn't expect is the car surrounding this great motor to be such a piece of junk. It rattles over every pebble, the passenger side window no longer works, and the "premium" speakers are defective and emit nothing but static when playing high notes. Overall, not worth $40,000. And the last BMW I ever buy.
