2007 BMW X3 SUV 3.0si 4dr SUV AWD (3.0L 6cyl 6M)
Worst New Car I Ever Owned
 I bought my new X3 a week ago and it is a total nightmare.  I did not know that there was a major engine hesitation with many of these vehicles, and mine is very bad and even dangerous.  The steering is not aligned due to either a wheel alignment issue or the wheel itself is not centered.  The controls including the navigation system are way too complex and awkward, and using knobs to control everything is absurd. My car has cosmetic defects on the fabric on doors and pillars, and it looks like they totally left out the quality in this SUV.  Overall, should have got the RDX.
