I just bought a used 2001 dodge stratus from a dealership. I bought it "as is" but the man orally said that if the car had any problems, bring it to him and he'll help with the cost. The car now needs a new engine. They said they will cover half of the cost, but should they cover the whole thing because I just bought it 3 weeks ago? Is there some sort of lemon law that can help me? please and thanks!!
