I bought X3 2.5, 6 speed, standard black, premium, leather.  I paid $200 over what it would have cost if we had done European delivery.  (You can price ED on the BMWUSA website)  My rationale was that my partner and I can fly for free, so why pay more that what it would cost us to get it in Europe?  Motorwerks said no way.  Sears took my offer in 3 minutes.  However, I was ready to sign immediately when they agreed to my price - that has a lot of value to a sales person.  My advice is shop, decide what you are willing to pay, then look for a seller and it will happen.
