I am never going to service my car here again. I schedule appointment everytime and they make me wait for 2 to 4 hrs everytime. This time i made an appointment for 2:30, it was 4pm and my vehicle was sitting in the parking lot. I got frustrated and demanded my vehicle back leaving me with unmaintained vehicle and a loss of day. There all smiles and service front of your face in front of money. Im never going here again.
