I was looking to buy a Subaru Outback and used Carfax to check titles on several. One thought one was great deal, come to find out it was salvage title! My next vehicle I found seemed to be the right car, low miles, ran well. I made an offer pending a good inspection. The inspection came out ok, but noted some oil leaks. I was ready to sign the papers, thinking it was minor. I re-reviewed the Carfax and it had noted which shops the car had been serviced. One appeared to do most of the service. I called them, they remembered the vehicle then told me the motor was bad! Carfax saved me $1000s! Carfax directed me to a local dealer where I finally got a good car in good shape.
