"We traded in the wife's Escalade in October and got hit with a couple grand in sales taxes. We already paid tax on the darn thing in Virigina. We didn't buy it here. But because we were trading it in, we got whacked anyways"

sounds to me that you were duped by the salesman, when a car is traded in the value of that car is deducted from the purchase price of the new vehicle and you only pay sales tax on the net difference.... if you still have the paperwork I would go back to the dealership and demand a refund
