Can a dealer sell me an "as is" car under deception

This is a follow up to my first question. The dealer sold me a salvaged car (witheld cars past AFTER being asked) ..this was not a private seller... the man who posed as a private seller name was not on the bill of sal. He just posed as the seller but the car was being sold by the dealer. Everything that has basically happened is that i bought the car ..it shut off within a hour of having it..i called the dealer he said so what you signed an as is paper . I signed the paper on the basis of his ad saying "GREAT WORKING CONDITIONS" and i asked the man atleast 3 times whats wtong he said I assure u nothing is wrong. He knew if he disclosed it being salvaged...with NO AIRBAGS...purge valve issur ($200) and timing chain $3000 repair I would NOT have bought this car..the dealer was in on everything as it was the dealers car the man was selling as if it his own... i had the car for 1 hour when I realized it had issues and 1 day before i found it the real MAJOR issues...he refuses to fix it.
