Audi dealerships near me (Chattanooga, TN)

Arrived at the dealership I stood all the sales room floor for over 15 minutes and was not even spoken to. Once I did locate the general manager the car that I was interested in was brought around and the wheels on it we're absolutely for all the pieces. They wanted me to pay another $600 to have the wheels painted. Why would I buy a good used car and have to pay more to paint the wheels? This car should have never been put on the lot in the shape it is in
