Check Engine Light On problems of the 2003 Volkswagen New Beetle Convertible

Car bough used from vs dealership on 7/31/2006. Been in for check engine light 4times, airbag light 3 times, a/c broke once, windows would not roll up once, needed new rotors once, rattling under hood once, battery died two days after I bought it and I had to tow it back to vw. Car jerks when going out of first gear-I told vw this repeatedly and they only tried to fix it after the warranty was up. They told me it would be $700 to fix. On 12/9/2008 my car would not go out of first gear while I was driving it. It had to be towed to my house and has not been driven since. I have had nothing but problems out of this car. I can not put anymore money into it. When the warranty went up, all of the sudden everything started going wrong. I requested prior information from the vw dealership about the other owner before me. I feel that this car was doctored so that I would buy it and then it started falling apart.
