I was in the market for a pre-owned car and decided to look on Craigslist. Of course I needed validation of what was being represented in the advertisement and knew of Carfax so that was my next logical step. When I went to the Carfax site, I was presented with 3 options, I chose what I thought was the best value with "Unlimited Searches" only to find out that unlimited means 5 VIN number searches and then unlimited if you know the, or the automobile happens to have a, license plate number. (Note to Carfax, not all cars for resale have a license plate.) As it turns out, the car I was interested in was "#6" so I was forced to purchase another search, which the site really doesn't want to do so I had to set up a new account as well. My question: Who makes the Carfax to check on Carfax?
