Too early to tell
 Presently have only 1400 miles. Haven't been too aggressive yet in the car. The engine sounds fantastic, but the car is definitely not a rocketship. The car turns a lot of heads, but it isn't real comfortable to drive. Hoping to take it out onto the local track to see how she handles under pressure. Except for the power mode setting, can barely feel a difference between any of the other M settings. Hopefully a little more time behind the wheel will help with the learning curve. We've had a number of other Beemer's - I'm still more comfortable driving the X5 or 550i.
