Hello there. Buying a used car is always very difficult since the buyer does not know what happened to the car during its operation! To facilitate this process, many people use Carfax reports, which help them see the entire history of the car and make decisions about its purchase. To learn more about Carfax, everyone can read the information here https://carfax.pissedconsumer.com/customer-service.html and perhaps someone will use their services when buying a car.
