Just another data mining scam. People are really just too uninformed to get how much of their lives are out there for the world.
It is none of your damn business how many time I get my oil changed. Suckers.
Well, I used carfax once and everything was absolutely great with the car we were looking at. No issues and nothing reported. Only problem was that nobody reported the accident it had been in so my one time buy for the carfax info was totally useless. DOH! Live and learn. I steer folks away from carfax whenever I can. If you can, a good overall eval from a trusted mechanic is the way to go.
