I forget the exact name, but I recall most dealerships have a form that can be filled out if they owe you anything as contingent upon the sale. I.e you notice a scratch on the car before you take ownership. You want an option added or removed. It should be documented and signed by both parties.
Most salesman get their bonuses tied to their survey results. So, if that survey hasn't been taken yet, I'd totally threaten to give them a bunch of 0's or 1's over the matter, and fill out a nasty review, until everyone can come up with an acceptable resolution.
Assuming this is a new car dealership.
