This was the worst service experience I have ever received. I was asked to make an appointment for an oil change, which I did to ensure they could provide the service in a timely manner. I was there for 3 hours for an oil change, when I was told it was going to take one. At any other garage this would have taken 30 minutes. I wasted an entire morning, and no one told me it would have taken that long. If they had warned me I would have gotten a rental and left. A lot of poor communication from their service department and no explanation for why the simplest service took an entire morning after already scheduling an appointment.
