I purchased a 2008 Mustang and it a beauty. I have no problems with the deal I got and nothing in that form. I asked how much it would be for Louvers to be put on and painted. The dealership manager said 500 for the louvers and I said ok. They went ahead and charged me 500 and I thought it was a done deal and had to wait for the parts to come in. I get a call today from the dealership saying they only said for the 2 side back windows to get done. I explained I have it in writing that the 2 sides and back window were to be done. The manager said it would be more money for them and he wanted to give me back the 500. I told them I had a deal with them and now they are trying to screw me cause they gave the wrong quote. They wont do anything about it and I have no idea what to do. I have called th Dealership top manager and he said it was for the 2 windows only and I explained it was for all 3 and I have the paperwork. What do you thin I can do to fight this?
