I'm also not a lawyer, but as long as you signed the agreement that they presented, then both parties are bound to the agreement.
Mike is also correct that if there is a clause where the bank can change the terms after the fact, then they could have wiggle room. This would be a pretty sleazy thing to do, and if it's a reputable bank, they probably wouldn't do such a thing. My question for you is did you read everything you signed?
It's likely that they've got some addtional incentive going on with the dealership. You should check to see what the difference in your rate would be. Also check with the dealership. If they do have an incentive deal going on with the bank, you might be able to get them to split the incentive with you, which might make the extra $1000 doable.
