Am I entitled to receive a refund if a used car that I bought broke down just after I drove it off of the lot?

Question Details:

Approximately 19 miles and less than 20 hours later the car stalled and would not start. After the dealer towed it back to their own lot I am informed that the car is not fixable. I put $500 down on a used car and signed a contract. I would have $324 monthly payments for the next 4 years. What are my options and how do I go about trying to get my down payment back for a vehicle that they still have in their possession without intention of repairing it or offering me another vehicle?
