With this car I have yet to have a backache. I have the basic X3. People think that the car cost 10k more than what i paid for it - even without leather seats. Turning corners is a rush especially feeling very secure with the vehicle. Can't rave enough about the steering. My 2.5i is enough.
Comfortable seating, accurate steering.
Hard to get to windshield wipers and making windshields difficult to learn.
