I needed to buy a used car without worry. There are so many choices out there and it's difficult to know anything about the history of a car, whether purchasing from a private party or a dealer. I had narrowed down my choice to a Subaru Outback. Now, the big questions were finding one that didn't have too many owners, was serviced regularly, and if it the car was an older model, that certain major maintenance service had been completed. I could only do that with CarFax. Not only could I find that information easily, but by entering license plate numbers of potential purchases, I could run unlimited number of CarFax reports. In addition, CarFax guaranteed the report so that my purchase was worry-free. I ended up buying a 2005 Subaru Outback from a dealer. The car was in very good shape. I am confident about my purchase thanks in large part to the service that CarFax provides. I highly recommend CarFax to any potential used car buyers out there.
