Dur Easy check in process when I arrived and service advisor explained what I asked them to do. I went to waiting area and had some coffee and snack. During the time for the service, I was able to get a little work done using the WiFi at the dealer. Service was completed in about the time they estimated. I paid for it at the cashiers office and it was parked inside ready for me to drive. Overall easy experience. More
