I purchased the X3 in Germany and have had the pleasure of driving 100+ mph on the autobahn for the last 3 months... sooo fun!! Handles like a dream, both in snow and on dry pavement. Steering is quick and responsive. The inside is roomy and quite comfortable. The size is perfect... large enough to pack everything I need and more, yet small enough that parking (even in Germany) is no problem. I didn't get the navigation system because I already had a Tomtom. I ordered a side dash mount from ProClip so the GPS doesn't take up space on the windscreen and the placement is excellent. Top quality vehicle!!
Seats that heat FAST. Large sun/moon roof is fantastic. Bluetooth works flawlessly. Park-distance-control is a real joy. There are a lot of little extras you can program into the computer (like having the blinker only blink 3 times when changing lanes).
Close to perfect. The only thing that would be handy is an automatic lift for the rear gate.
