3 weeks ago I purchased a 1999 Oldsmobile Alero. We agreed on 2800 for it with all registration done. The car at time of purchased was marked as 4 cylinder 2.4L model as stated in paper work and I wanted that model for mpg but within 2 weeks of owning it I had major problems. 1 Tire blew out and I had to spend 400 replacing all 4 tired, check engine light came on twice, needed new struts and was quoted 700 for them and fuel economy was far below what they advertised to me. Yesterday I had mechanic look at it and the engine was a 3.4L 6 cylinder model not the 4 cylinder model that the papers said. that's 10mpg then what I wanted. Since all the paperwork is wrong and the model they sold was wrong (Right vin# though) can I legally force them to take car back and refund me?
