 First time BMW owner, a solid car, fun to drive, break is strong and smooth, precision steering, communicative road feel, wish had 535i, power is okay, but feel a little weak when loaded with 5 people, Navigation told me to get off every exit on NJ TPK for no reason and then get back on no matter what mode I select.  One time when fuel was low, the car was driving rough and jumping on the road, stopped the car, refueled, and restart - the problem run away.
