The AutoCheck database contains 4 billion records on 500 million cars.
However, the reports may be missing some information if the repair was carried out by unauthorized services. Despite this, AutoCheck is considered the most reliable auto history check system in the United States.
To purchase a used car from America, it is recommended to purchase an AutoCheck report by VIN.
The Carfax and Autocheck databases are direct competitors to each other, but AutoCheck is more efficient and provides the most complete information on mileage and accidents.
