I bought a used car from a car dealership, and a hour after driving it off the lot I realized my horn did not work, in addition to other issues that were not as major. I took the car back two days later, but they would not take the car back. I have only put down $500 down, and the other $500 I am supposed to pay this week. However, I would just like to return the car and receive my down payment back. Any advice would be greatly appreciated.
