I bought a used car and immediately I had problems with the car they fixed it once when i was not under warranty anymore, only because it broke down on the way to the dealership and then I had issues again now they do not feel they have to pay for it. I have evidence that I emailed them about what was wrong with the car before the warranty was over. What I told them was wrong months ago ended up beign what they had to fix this last time. They do not answer my calls and are rude. What can I do legally?
