My only real complaints are the newly developed clicking/creaking/ticking my driver seat has developed. If I really change the seat around...all the way back, all the way forward, up, down...then the noise goes away for a while. But, it then comes back.

And that the USA spec X5s are not offered with UV/Thermal glass. We have UV glass in our '11 Range Rover and I had it in my ML63 and both Lexus suvs. It makes a HUGE, HUGE difference.
