I just want to know how reliable you guys have found Carfax to be. I am not too sure about it. First off, when my mother traded her Passat in they brought up the carfax and it said that the airbags had gone off. It was in a mild front collision but the 'bags never deployed. Then on my 4Runner, it has all the maintanince records from the previous owner, but says the timing belt was inspected at about 100k miles. I found a site on this forum where you can look up your VIN and find out the history. It came up with all of the same records but said the belt and water pump were replaced. I am not sure which to believe and do not want to have to pay to do the job that may have just been done. Also do not want to risk it having not been done. What have you found in the past?
