Stay away from this model year
 First, I will say that this car is one that is fun to drive.  And I have not driven a car that performs better (steering, engine performance).  People have written about the high cost of fixing all of the little things that DO go wrong with this car.  However, once the car has been returned to me I fall in love with the car again and again.  My major problem with the car is that this car has serious reliability problems.  I have experienced two problems that show up many times with other drivers of same vehicle.  One problem is that this car has a weak subframe that has a tendency to CRACK (BMW fixed for free -  see class action lawsuit).  Also, see issues with transmission.
