Create a line for the seller and buyer information. The first line of your contract should state that the seller agrees to sell the buyer the vehicle. Make sure to include the full legal name of both seller and buyer and include the make, model and year of the vehicle.
Include a section that details the date of sale and the used-vehicle price. For example: "The date of the sale is Feb. 22, 2009, and the agreed price is $2,000."
Disclose acceptable forms of payment. This is the section of your used-vehicle contract where you state what methods of payment are acceptable to you. For example: "On the date of the sale, the seller will accept only cash or a money order from the buyer."
Include a section that discusses your responsibilities as the seller. For example, on the date of the sale, you may promise to furnish the vehicle title, registration and odometer disclosure statement. Since the vehicle is used, you also may want to provide proof that the vehicle has passed a recent smog inspection.
State that the vehicle is sold in "as is" condition. When selling a used vehicle, it's important to include language about the vehicle condition. For example: "The vehicle is sold in 'as is' condition, and the seller makes no warranties about the condition of the vehicle."
