Hi from Perth!
There is a site (I haven't been there) that decodes your VIN and gives options fitted and delivery country (ie spec).
Sun roof after factory MASSIVE hassle. If the car is what you want, other than the roof, then take it. A lot of BMW's here are South African spec.
Enjoy your ride!
Good - Fast - Cheap: Pick any two.
