Too many problems
 The car is good performance wise, fast, fuel economy better than expected. But it is not reliable and poorly built. Had problems with the retractable hood, steering wheel jammed, side windows not going down, memory reset all with in 18 months of ownership. Even today, sometimes when I close a window it goes all the way up and then comes down and one has to repeat several times before it shuts. After filing a formal complaint no action was taken by BMW. I have paid a lot of money for the car and at least expected a formal apology. Will never buy another BMW.
