If the contract and paperwork says AS IS you do not have any warranty weather its new or not. There could be a few reasons why they do this but they obviously have a reason. I would be more than a little hesitant to buy anything when the dealer was so obviously hiding something from me. You might want to take the VIN and call Thor to find out why. It may have had a water leak that has been covered up or some structural damage that could not be fully corrected ect. and Thor auctioned it off to recoup some cost. Check to be sure you dont have a salvage title. AS IS does not just absolve the dealer but everyone involved, Ford, Thor, the chassis stretcher everyone.
