 Well German engineering aside this SUV has been the worst new car I have ever owned in 30 years of driving.  It lives at the dealer.  So far still cannot fix the hesitation issue which is severe in normal "D"; moon roof significant issues: needed new exhaust at 40K miles: blower motor issues; navigation system is major piece of junk: now satellite radio is defective and no parts to fix it; X drive is lousy in the snow not really a true AWD system; etc.  Horrible vehicle trying to get out of the lease early.  When get loaner car usually a 3 series love it.  X3 is just a BMW fiasco stay far far away from any of these until they redesign it.  Oh love heating steering wheel.
