CarFox had saved me from almost buying a car which has a structural damage reported on it, I would have ended up buying a car which has accident reported on it if I did not check CarFox. This is an amazing app and it helps a lot in buying a proper car especially when you are shopping for used cars, I would recommend everyone who is planning to buy pre-owned car to buy CarFox and check the VIN's. Even if you plan to buy a pre-owned from a dealer I would highly recommend to have your own CarFox to check the history instead of relying on the reports provided by dealer as they can be manipulated.
