Are you doing ED and performance center delivery? I can't really answer your question but I do know that for those going to SC to pick up their BMWs that they have on order, it's usually a few weeks later than if they just picked up their car at the dealer. I think this has to do with scheduling, financing, all the other paperwork, etc. so I don't know if this applies in your case.
