This is my 2nd X3 in 6 months. I had so many problems with 2007 that BMW bought out my lease and I ordered another one (would not let me totally out of the lease). These are overpriced and not up to par with Japanese vehicles. Problems-- transmission does not mesh with engine, hesitation, brakes grab, OEM tires were AWFUL in snow last few weeks, took them off before slid into something. Navigation system is archaic. Radio even upgraded one just does not provide quality sound. This is definitely not the ultimate driving machine. I would never recommed an X3 to anyone else. I do not know how other reviews are favorable. Guess just taken away with BMW emblems all over the car.
Navigation. Engine/transmission that work together. Decent OEM tires that grip the road. Better sound systems. Make an alarm standard.
