The experience at the store when having my E350 wagon serviced has always been good to excellent. Most recently, when I scheduled the most recent appointment I was told on the phone by the scheduler that my car was only due for oil change, and could be done in a couple of hours. When I met with the service advisor the day of the appointment he said it needed a lot more -transmission fluid/filter change, cabin air filter replacement, and more. It was $1000 more than I was expecting and required me to leave the car overnight. They provided a free loaner but I wish I knew ahead of time it was going to be more time and money commitment than I was lead to believe. None of this constituted a "bad day", it was really a minor glitch. Overall, the dealership has been very good to work with. They really seem to want to give their customers a very positive experience.
