I ordered an '04 through my dealer. When I finally received the production number from him and checked the status on BMWUSA's Owners' Circle site, I discovered that the car has already been produced and is awaiting shipment. However, one of the options I ordered was omitted (probably a dealer error). Does anyone know if the factory can install the heated front seats option after the car has been built? Or, will the dealer have to put in a new order?
