Hello again, Mark.
If you can post the documents here, I could view them. The language you provided does not make the agreement to purchase conditional on obtaining financing though. It just indicates you will execute other documents as may be necessary that is consistent with the terms you have agreed to.
Unless there is something in the contract indicating that the agreement to purchase is conditioned upon obtaining financing, then both parties would normally be bound by the terms of the agreement. If the financing fails though, that would typically provide a basis for either party to terminate the agreement since one of the material terms of the contract have been rendered impossible through no fault of the parties (although it is arguable that the dealer should have requested proof of income sooner--that may be the fault of the bank though if they delayed in requesting that).
So, you could normally terminate the agreement if you cannot come to an agreement as to the terms of financing, PROVIDED your purchase agreement does not state otherwise.
I hope this helps clarify the situation for you.
