Vehicle mileage is often tampered with to artificially inflate the value of a used car. Using complex software, some unscrupulous car dealers will take thousands of miles off the odometer of their used cars. This allows them to sell the vehicles at a higher profit margin. If you want to check out the mileage on a vehicle for free, there are ways to do it.
Step 1 Visit the CARFAX free odometer check page at carfax.com and enter the car’s VIN number. You will receive the car’s last recorded odometer reading free of charge.
Step 2 Contact your state Department of Motor Vehicles and request a title search for the vehicle in question. Compare the mileage on the title to the mileage on the odometer. Titles may also be forged, but title information received from the DMV is less likely to be fraudulent.
