Carfax is expanding the service information in its reports, providing a better understanding of how a vehicle was maintained. Now, more detailed service records are displayed in all Carfax Vehicle History Reports. Consumers demand this kind of data to help them make informed decisions about a car's past performance and future roadworthiness.

Potential owners see detailed records of routine maintenance, such as oil changes and tune-ups, along with more extensive information like damage repairs and parts replacement, when available. The service history displays the name, location and Web address of each shop that provides maintenance information to Carfax.

Prior to purchasing a vehicle, used-car buyers should request maintenance records from the seller. Carfax also strongly recommends having an inspection performed by a trustworthy, reliable mechanic. Combined with the Carfax report, this information may help uncover any hidden problems.

Carfax reports list all information reported to the company for a specific vehicle. Consumers can check a vehicle's reported service history by visiting and entering the 17-digit vehicle identification number (VIN). Cars purchased with Carfax Vehicle History Reports that do not contain DMV-reported incidents (salvage, fire, flood damage, odometer problems, lemon history) may be eligible for the Carfax Buyback Guarantee.
