bradgarbus,
Call your salesperson.
I sweated the $$$ leading up to my sale too, because my Credit Union is in MSP, my dealer is in PDX, and I was somewhere in between.
I called my saleperson and he was able to provide a sale sheet for the total cost that I faxed to my CU. The CU dropped the loan proceeds in my account before I headed out to PDX on Amtrak (a nice way to go, BTW). And I wrote a personal check to scPDX when I took delivery.
Good Luck and Happy Trails!
Timo
