Wow I feel bad for you. I have been looking at Certified cars out of state and your problem is tremendously upsetting.
I would find out if there is a law in MO that covers recently sold cars.
I would have an attorney speak on my behalf with the selling dealership GM.
Man I hope this can get a clear resolution.
