How badly am I being taken advantage of by this shady car dealership..?

Hey guys. To make an entirely long story short I will first state that I am a 20 year old college student from Connecticut who went to purchase a used 2006 chevy cobalt ss (5 speed) from Northshore Chevrolet of Smithtown in Long Island New York. This was my first time buying a car and I had saved my hard earned money on it. The sales rep insisted that the car was in perfect shape and several mechanics had taken a look at it. I thought I could trust him but I asked him if I could get it inspected by a mechanic at home and he kind of hesitated but agreed. In any case I had the car for two days and the clutch began slipping. I've driven manual for 4 years and know that it wasn't my lack of experience. I didn't race with the car I literally owned it for 2 days. Another thing I noted was that when I parked on my hill the car would roll back even with the ebrake up. I asked around and was told that the previous owner must have been a racer because of several after market modifications including an exhaust, cold air intake, and towering strut. Also the fact he was a racer was evident because my friends informed me that ebrakes become damaged like that due to drifting and that the clutch was probably beat to the ground. I was worried about the safety of my car and life so knowing how badly the clutch was slipping i called AAA to tow it to a local GMC dealership. The mechanics checked it out and told me that not only was the clutch ruined but it damaged the flywheel and several other parts. The ebrake was completely worn and the rear brakes were gone. Also the tires were stripped bare. I called Smithtown Chevrolet back inquiring about repairs and they informed me that it was probably my driving because world class premier mechanics had checked it out blah blah blah. Anytime I tried to get answers I would get the run around. I was so fed up I started writing several complaints on their dealership and called GMC/Chevrolet HQ. I was informed that the clutch was a wear item and it couldn't be covered. Now they're trying to tell me they'll split the cost of the brakes but under the New York State Lemon Law it says that dealerships must replace faulty parts such as brakes within a time limit. My issues were almost immediately after my purchase. I am in need of some serious help please! I have called these guys about 12 times trying to get them to repair it but they will not own up. It just seems so unfair that they sold me a car that was obviously a lemon and lied about it.
