Even a Car Fax on a car can be dubious. For instance. Someone gets a car from the original owner with no
collision history, so thus no
record of mileage over the years. You replace the speedometer module in the dash with a low mileage one. You then sell the car with this low mileage stated. Everything on
record shows only the low mileage statement. But it may have over 100,000 miles on it. Don't ask how I know!
