I'm kinda going through the same thing right now. I have a post out there as well titled should I sue or something like that. I paid big dollars for head gaskets to be replaced which is expected but after 5 return visits the car still doesn't run right. Anyways if you paid by credit card, file a dispute with your credit card company. If you can prove your claim they will remove the charge permanently. Or theres always small claims or call the dealership, get the owners name and write a letter directly to him. Be cordial, but if needed, threaten legal action. As a single woman several businesses "have seen me coming" and I felt as if I had gotten ripped of as well. I have tried the above remedies and they have always worked for me. All will take time but if you feel strongly about this it is worth it. Good luck.
