Carfax is a good tool when purchasing a new or used vehicle for the most part the information provided is accurate up until the last buyers purchase it . I do not like that you only get five Vin number checks if you purchase the unlimited went in the past unlimited was unlimited for a longer period of time. Wether by Vin number or tag. I searched for a new vehicle with little luck Carfax did help to identify those vehicles with the rollback mileage which is very common nowadays. And I purchased 2 owner Nissan Armada with accurate mileage and good service history for a great price for the new family . Baby Lucas says ,thanks Carfax !
