Well, IMHO the BMW dealership should just have to put up with it and take a hit by selling it to you. But, i just spoke to my father who is always on eBay and he told me that having a Buy it Now on a item pretty much acts as a reserve(reinforcing what Laszlo said). That the buy it now is the lowest price they will sell at.Then again my father can be wrong...Hopefully he is
because i believe that is complete BS.
Good luck and keep us the updates coming!
