I set a appointment for noon on Saturday, received a call right before they closed but j missed it, i call them back and was told to call in the morning to confirm. Called in the morning and was told they don't do appointments on the weekends and its been a known issue they haven't fixed. Service manager said they could get me in at noon and offered a free car wash when the special already includes that. I told the service manager the price on their website for an oil chance is 34.99 yet they still over charged me it, I didnt have time anymore time to argue it so said screw it and just left cashier was rude. I was suppose to get a call back over this issue but never got one.. I won't be going back to this dealership.
