I've had my '04 X3 for about a year and I absolutely love it! Fun car to drive, very reliable, great maintenance program, handles great in snow and rain and nice peppy engine for merging onto highways. It sure beats the VW I sold to get the X3!
Moonroof is awesome! Heated seats are great. I like the small orange light that illuminates dash at night. The express up/down back windows.
Should have cruise control, 6-disc CD stereo and fog lights standard. It needs bigger glove box and more storage for small stuff.
