Conduct a walk around of the vehicle. Is the condition of the car commensurate with the age of the car? Look at the gas and brake pedals- if they are worn yet there is very low mileage on the car, there is reason for suspicion (possible odometer fraud). Look under the hood- are the belts and hoses worn and cracked or have they been maintained? How is the paint, dents scratches? Check for the original manufactures vin plate in the side of the door, hood, and trunk. If it is missing, it's possible the vehicle had been in an accident and that panel of the vehicle was replaced. Obtain a vehicle history report!
