Took my brand new A8 in for service and while there they rear ended my car and crushed the back end. They tried to hide it and say they just "dinged" my car until I went to the body shop were they had quickly taken my car. Worst dealership I have ever dealt with. They lied about what happened and never apologized for what they did and now I have an A8 worth much less because its been in an accident. Avoid this dealership at all cost!!!!!
