Yes, the tax liability is yours, based on the selling price. It's quite easy for a dealer to recalculate the selling price to meet the amount already collected from you so there is no outstanding tax. He could also just pay the balance. Of course, either of those steps means cutting his profit.

$1K short seems to be quite a bit of an error. Go over your paperwork and see if you can find the error. You might then, given the respray that apparently wasn't disclosed, renegotiate the sale to match the amount you've already paid. Depending on the wording of the contract, you may also be able to cancel the deal altogether. A lot depends on the contract.
