New Kingstown Auto llc Sold me a total lemon Mechanicsburg Pennsylvania

This so called auto dealer sold me a truck that had some rust on it, when asked if the rust was the only issue with the truck was told yes. I am a first time auto buyer and wasn't sure what to look for and certainly did not think someone would sell me a giant death trap. The truck was sold to me for twice what it was actually worth, and I ended up having to pay 3 times that in repairs to attempt to get this truck to run safely and be inspected. The mechanic took pity on me becasue of the absolute terrible condition of the truck but told me that these people sold me a worthless piece of metal on wheels. That it had to have been a car that came from a state that required NO inspection as it would not have passed by a long shot. Unfortunately PA's lemon law is a flawed thing and I can't go back to the dealer to have them right this utterly terrible wrong. I hope that no one ever buys a used car from them again...I am so in the hole with this truck :(
