I purchased a modified ///M3/4 from my local dealership less than two months ago. Here are my problems. First the General manager had the car worken on before I bought it. He had a tv removed from the dash. The work was done improperly and caused the cd changer not to work. I took it in to be fixed and was given a bill whan I left. Second the car needed a clutch when I bought the car. But they want me to pay 1100 dollars to do it. What should I do? It was a Certified car and I need it fixed asap.
