When checking a CARFAX report, it's necessary to be mindful of any discrepancies that may appear in the odometer reading. As a dealer, you must ensure accuracy and confidence with the vehicle you're selling.
It is possible for an inconsistency to arise between sources - for example, if Nevada DMV registers a mileage at 4,000 yet an auction company marks the same vehicle at 100,000 miles three weeks later, it likely does not make sense.
CARFAX's support team can assist with correcting any discrepancies found within their reports; simply go to "Help" on their website (https://www.carfax.com/), click "Report Discrepancies", and choose either “Request a Correction to a Carfax Report” or "Why are Accident or Other Details Missing". It's better to get the right answer than spend time and money fighting false claims in court.
