Carfax is amazing, it is really easy to use and usually gives you a good overview of how the car was maintained, how many owners, mileage, how many miles have been put on it every year. It helped me find my vehicle, It saved me from buying a lemon once which I'm grateful for because it would've been a lot of extra money that I wasn't willing to spend. I was going to buy a 2003 Ford Escape, and I ran a carfax before I was going to purchase it, and it blew my mind what I found out about it. It said that in 2008 it had 180k miles already, and the funny thing is I was going to buy it here in 2015 and the odometer said 127k miles. If you put the numbers together who knows how much miles it has, I later saw that car selling again because it broke down. THANK YOU CARFAX, you saved me money and time :)
