4.9% and $2500 credit for 2010??

[drod]

I finaniced my 08 model through BMW and have been able to double my payments in order to put it behind me sooner than later...

i'm sure this should put me in a better position to negotiate a better rate when i purchase a 2010 model.

thanks to this forum, and the invoice numbers that were available, I have been able to successfully negotiate somewhere in between invoice and MSRP on vehilcle price and options.

but I'm not sure how this $2500 (if that is the true number) applies...

can I still go about negotiating the purchase price, then expect an additional $2500 credit?

what dealer "play" should I expect?
