Overall car is fun to drive, the performance is what you would expect from a BMW car. The appointments in the car are first class, but there is one thing that I see lately, which has frustrated me, and many other people on the Bimmerfest forum's...that is a terrible whining noise coming from the transmission or differential....drives people crazy !!! I seen the same issue now on 5 Series and 7 Series cars, and BMW doesn't seem to care about this, but it totally frustrates many people that have spent a lot of CASH!!!
