My CARFAX story involves selling a car. When we took the car to the dealer they pulled up the CARFAX sheet for it and pointed out that we’d had an accident with an airbag deployment, making a lowball offer for the trade in. While we had, in fact, had the accident, the airbags had not been deployed, and this was the sticking point in our negotiations with the dealer. So we worked with our insurance company to get documentation from the accident to confirm that the airbag had not been deployed. We submitted this information to CARFAX, and within a day or two it had been corrected. CARFAX also sent me a complimentary copy of the revised report, which we took back to the dealer, resuming negotiations. I was pleasantly surprised by how easy it was to get the report updated.
