for whatever they can, whenever they can. There is no formula you can apply for the value of a car. I've checked with Car Point and NADA, as Andrew suggested and find a $5k discrepancy between the two services on the price of a '99 Chrysler Ltd. NADA was $5k higher than Car Point????? I'm going to try to find some other services and get an average before I go to sell/trade it on a new one. As far as your dealer's having linked to a service which they ignore - there's nothing that can be done about that except to do your research and then, well armed, go after them and make YOUR deal.
