Lake City Auto This company sells lemons. They will rip you off big time morrow Georgia

This company will rip you off big time. I purchased a car from them 04 pontiac grand prix 182,000 miles for 6000. I know that's too much but I didn't have a car at the time and it sounds good for 1500 down and 300 a month. Now that I'm almost finished paying for the car which has almost 200,000 I was late one month on payment. They repossessed the car and gave me one week to gather 930 three times the amount I owe them. Once going through hell and back to get the money together I was thinking they are about to take the car away from me. I have less than 1500 to pay them before getting the title why would they try to slide it from under me this way. Once paying them I noticed the car looked different. They informed me they changed my new tires out  because they had slow leaks in them. Wow! Immediatly I searched the car and noticed everything was missing like a diagnostic system I rented from auto zone, amp and speakers that I've had bolted into trunk. My CD changer and random items around the car, Gas was missing. Someone even opened up old check stubs I was storing. Why would they repo the car after one month, 30 days on the nose. Then strip the car down and gave me one week to gather 900. I should of took my 900 some where else and put down on another car. The car doesn't drive right as if other parts are missing. I took my contract to a lawyer who told me the contact is unbelieable. Please don't buy a car from them they are ripping people off. I wish I would of let them have they car after repo. Its not the same car I invested all my money in.
