Agreed that you should really scrub the paperwork. The taxes should be a known commodity. I have a used vehicle dealer's license in KS, I collect 7.5% sales tax from the customer on the net sales price and it is paid as part of the gross purchase price, i.e. one check from the customer. After I collect the gross purchase price, it is on me to pay the correct sales tax to the state. In the event that I miscalculate the sales tax, there is no guidance regarding who is liable. Personally, if it was my stupid mistake I would pay the correct sales tax out of my pocket and move on.

Being that you traded in a leased vehicle, I wonder if they screwed up the positive equity side of the equation and listed the vehicle at a lower net (taxable) sale price? Whatever they did, $1000 is a big mistake.
