You could probably just sell the spare, jack etc to another BMW person on this site and purchase the parts from the dealer. I guess it would just be the surround plastic frame. Also, search this site for people who have make the switch the other way, it will give you a good idea of how everything looks. Also the X4 which is basically the same car, has a spare but it does not raised the rear floor.
