Sounds like Carfax is trying to drum up business. I would not trust them with anything. Had a truck that got hit three times, all reported to insurance and the truck was fully maintained at the dealership. Person buying it got a Carfax report and the report said no accidents and no maintenance has ever been performed on it. Showed the stack of records to the buyer and he was fine with it, just unhappy that he spent money on a useless report and had turned down other trucks because of the lack of maintenance. Also worked with someone that bought a vehicle based on the "one owner, no accidents" report. When he was adding some equipment, he found that there were at three doors that had been different colors and lots of body work had been done. Carfax said "sorry, we missed that" and that was it. Would you trust them?
