Carfax and AutoCheck are two services that provide free auto reports by fax. Carfax provides a full vehicle history, and AutoCheck provides the vehicle identification number plus information regarding any accidents involving the vehicle.
Customers who shop for cars on the Carfax website have free access to the full Carfax vehicle history for each car listed. The vehicle history includes the car's title history and mileage history, and it often also includes information about accidents and the car's service records. The Carfax report is also available for free from many used car dealers. AutoCheck provides mileage history as well and issues special reports when a car has been deemed a lemon, has had the odometer rolled back or has suffered water damage.
