Business ProfileforCar City

I purchased a vehicle through Car City on the 4th of December, and it was delivered the 12th. Upon the first drive, it wasn't shifting properly, and the check engine light came on. I took it in to a shop and it needs $700+ worth of repairs. The warranty company agreed to pay for the repairs since its before the 30 day ***** Upon driving, was pulled over and the "proof" Car City gave me in that event weren't considered sufficient, and my vehicle was almost impounded. I had to BEG the officer not to take the vehicle as its my only transport for my son who is currently fighting stage 4 cancer. He let me take it home but said he'd be watching the area closely and if I drove it again before I had the physical registration or title, it will be impounded. Mind you, the sales manager advised me that the proof they sent me via email was sufficient to drive with until i received the registration and title. I was ticketed. I called them and all I was told was to basically argue with the officer next time because it typically works and is legal. I contacted SOS and they too said I needed a temporary plate and registration until mine was transferred. I am not longer comfortable doing business with a company that does all of this without any help or warning, but am told I cannot return it. I have decided to consult with a lawyer because this cannot be right.
