Generally speaking, when a buyer defaults on a contract for the purchase of goods, the seller is entitled to damages for the buyer's default. The amount of the damages may be limited in certain cases, sometimes to $500 or less. It is not clear from your question what the value is of the money or property retained by the dealer.
