Looking to purchase a 2004 and located one at a Dodge Dealership that according to the saleman, was a "Replacement Vehicle" buy back from Dodge. He said that the vehicle was purchased new and that the car exhibited "engine vibration". Dodge bought the car back (lemon law) and then replaced the whole engine. According to the salesman, Dodge was the one who replaced the engine. The car only has 3k miles on the odometer and is spotless. The car has two years left on the manufacturer's warranty. Excellent price (due to the circumstances). My question, is it worth purchasing a car that was bought back and had the engine replaced? What am I getting myself into? I figure I'm saving about ~$5k from comparably vehicles that I've considered (2004's with the same mileage). I appreciate the input!
