I found the X5 to perform much like a sports car and not like your standard SUV. The handling was supreme to any other SUV I had test rode. The step up height is low and the size of the vehicle was not overwhelming like the american made models. I love this truck!
The HUGE sunroof.
Have a DVD player installed in the armrest that can flip up so the rear sit passengers can see it. This is much better than a ceiling mounted unit, since it does not distract drivers behind you "peeking" at your kids movie!
