Autoquest was selling a 2007 Porsche Targa via Ebay. The AutoCheck report with the car showed no accidents. However, I purchased a CarFax for the car and it showed there had been an accident and airbag deployment in 2007 which AutoCheck did not report. I had been told by others to always do a CarFax because autocheck was incomplete. I contacted the car dealership and they said "oh, this isn't good". They seemed surprised but my belief is they could tell the cart had been repaired. In future, i would recommend everyone get both carfax and Autocheck and not trust just autocheck or a car dealer that only uses autocheck.
