Carfax is a popular web based used car report facility that is strongly recommended for all used car shoppers. Carfax collects its information regarding all the used car it has on its list through multiple sources.

Carfax used cars reports contain the following information about the used cars on its catalog: records of previous owners including duration of ownership, issues with regard to titles or lien, mileage covered, service and maintenance records, warranty period, previous records of accidents and damages caused, destruction caused by fires or floods, recalls or buybacks of manufacturers and whether the car was used as a fleet vehicle and so on.

Like with most things that can or cannot be verified fully, Carfax used car history reports too are not a 100% true or legitimate. Details gathered from its sources are trusted completely by the company and it is clearly printed as a disclaimer in its reports also. This is because, although its various major sources share a variety of information, how many details are missing from disorganized departments or from very small repair shops in nondescript towns across the United States and Canada is just countless. Also, some repairs or services done by unnamed private mechanics or friends or family might not be reported at all or reported ambiguously as a replaced or reconstructed part.

In spite of these drawbacks, Carfax reports are still reliable and respected because it is valuable for potential used car buyers who feel some information is better than nothing at all. The best thing to do is to check the used car thoroughly, inside out, with the help of an experienced and knowledgeable mechanic and also test drive it yourself. Feel the vehicle and follow your intuition for a good purchase.
