Auto Depot

I bought a car roughly 3 weeks ago from these guys. Two days after I bought it the check engine light went on. After taking it back the owner told me that there would be no problem, due to him selling it with a warranty.
I took it to my local repair guy «Marty’s Motors» and they told me that the car had in correct spark plugs, the sensors might be bad, and its possible that it may need a valve adjustment ($ 950). I called the warranty company and they told me that none of this stuff was covered, The warranty is only for major replacements, NOT REPAIRS.
I went back to Auto Depot, and talked to the owner who is still giving me the run around. At this point even if he was to take the car in himself and fix everything I still feel burned. I hadn’t even put 100 miles on it, before the check engine light came on. This tells me that they absolutely knew that there was a problem, and only offered a warranty as a band aide to the sale.
I would never do business with these guys, and I would discourage anyone else. This is how the Used Dealers got there bad name.
(I bought a ACURA MDX which is not a cheap car by any means.)
