its just a tool to aid you in the car purchase, not an end all for used car buying.
people believe in it, so use it when you sell your car.
Also anything that has to run through the DMV will be on there; stolen car, totaled out, incorrect mileage report ( swapped cluster ), lean on title. You know, the things a mechanic might not be able to physically see.
also they have a buy back guarantee, but its too early in the morning for me to read the terms
