Auto body repair service near Pontiac, MI

This is a terrible facility. The quoted me an original price of $927 for labor on an R and I engine repair. They kept my car without doing the work and when I came to ask for my car to be release the owner threatened my by putting his finger in my face and called my an F***ing A**hole. I wanted to just get my vehicle completed by the estimated time he had given me. Things escalated and I called the police. They gave a new invoice for $2217. Took the issue up with the state and they were sanctioned. They were told to release my vehicle but the refuse so now we are going to court. They never finished the car or never planned to even if I paid the $2217. The owner said that he would enjoy make good money off my Porsche when he sales it. The state has denied any attempts at putting a mechanics lien on the vehicle and has told them to give it back.
