CARFAX helped us avoid buying a lemon. We had made plans to drive 3 hours to get my dream car, and at the last minute I purchased a CARFAX, just to be sure. I discovered that the car had been in several accidents, had more owners than we were told, and had 80,000 more miles than the odometer showed. Obviously something wasn’t quite right, so we didn’t end up making that trip. We dodged a bullet, thanks to CARFAX.
