Deals On Wheels Sold me a LEMON!!! Wilmington, Delaware

I recently purchased a vehicle from Deals on Wheels in January 2013. The vehicle has been NOTHING but problems since I purchased it. It has been to there shop at least 8 times now and every time I am told I don't qualify for a loaner car, I was even told by the GM to ride the bus? The very next day after I bought the car I found out there was a leak in the emissions, which I was told would fail the car's inspection but yet they claim ALL cars are DE inspection ready?

I had to get a new tail light, 2 thermostats, head gasket, 2 new tires, new battery, numerous different hoses replaced, coils, rocking arm (believe that's what they called it), . The sad part is they had the car more than I have. When I had my head gasket replaced by them I was told it would be a 12.5 hr job and should have my car back in no more than 3 days, 12 days later i FINALLY got my car. The very next day the car broke down and had to be towed back to the dealership. I don't know how this place is still in business and isn't shut down, they have VERY POOR customer service and speak to you like your a child.
