I work at a used car dealership and people always want to see the Carfax. We are a Carfax Advantage Dealer, meaning that we pay a fee to receive leads, discounted report pulls and some advertising merchandise. A few months ago, I found a discrepancy on the mileage of a diesel flatbed truck that we have for sale. I called Carfax and they required proof that the miles were input wrong. I sent them the Colorado emissions report and they said it wasn't good enough. I called the repair shop, listed on the report, that had worked on the truck prior to us buying it. They admitted that they fat-fingered the mileage and would take care of it. I pulled a new report yesterday and the discrepancy is still there. I called the repair shop and they said they they had spoken with Carfax months ago to fix the problem. I called Carfax again, spoke with Ana, and explained everything. She told me there wasn't anything they could do unless I provided proof that the other shop messed up. It's like going around and around in a circle. She wouldn't even pick up the phone and call the other shop, taking me out of the middle, to get it handled. She also wouldn't provide me with contact information for her supervisor to get this resolved, saying that she was the end of the line. Carfax collects money from both ends, dealerships and consumers, and won't do anything to help when there's a problem. I will be looking at changing to AutoCheck, or just printing the NMVTIS report to show no known title issues.
