It is important to complete an auto bill of sale form when selling or buying a used car. For the seller, an auto bill of sale form provides proof that title to the used car has been legally transferred. For the buyer, the auto bill of sale form documents the purchase of the used car. The auto bill of sale form should contain:
1. name and address of the buyer; 2. name, address and signature of the seller; 3. complete vehicle description, including the Vehicle Identification Number(VIN); 4. description of trade-in, if any; 5. purchase price of the vehicle.
