I have owned the car now for about a week, and it performs very well. I don't find any hesitation as some reviews have stated. What some call hesitation is the engine coming up on the torque curve, not a transmission problem. I would like to physically be able to check the oil instead of depending on the computer to tell me that it is O.K. This is a great automobile, as every BMW I have owned was.
The engine and transmission perform very well together. The sport suspension is just right, not to stiff. It is a sports car wrapped in an SUV skin.
It needs an actual engine oil dip stick. The brakes are a little touchy, but good. The car is a little pricey for this size vehicle, but that is BMW.
