Ordered a 2013 X3 28i for my wife on 12/07/12:
Space Gray Metallic
Mojave Nevada Leather
Convenience, Cold Weather and Premium Packages
Park Distance Control
BMW assist w/enhanced BT/USB
I drove this and the 35i and found the 28i more responsive; the Auto start/stop was interesting; I thought the car had stalled; will take some getting used to as well as the gear selector; can't wait until it arrives.
Got what I thought was a very fair deal after some extensive research here and through some other sources.
