LOL, my help could save them lots of money when someone goes to buy a Ferrari whose history isn't listed in a Carfax, and they decide to turn around and sue Carfax. And I, personally, have no need for a Carfax account. At least not now anyway.
Read the warranty about their information. They only have to buy the car back if the information they have is not accurate meaning if they don't have the information that doesn't mean the information they do have is inaccurate. It's a catch 22. The person from carfax who pmed me did say they have bought back cars in the past, he didn't say why. It's like a car dealer that says "we guarantee the lowest price or the car is free" guarantee. It is practically a worthless guarantee.
