Merchants always use a sales contract to conclude a sale, and it is an agreement between the buyer and the seller. However, if you buy a vehicle from an individual, you must sign a sales contract for the individual, which is a simplified form of sales contract. This is necessary so that the individual can prove that he is no longer in possession of the vehicle if the vehicle is involved in an accident or if the vehicle has been abandoned. The Bill of Sale can also serve as a “pink note” for the buyer until the paperwork for the new owner is complete. Dealers use a car purchase agreement or a car purchase agreement to conclude a sale. These contracts serve as a sales contract between the buyer and the seller. . . .
