sl550 service
routine B service was performed with good satisfaction. No problems but in at 8:45 and out at 3:45. That was too long far a short service. Still I was very pleased especially without the usual call saying we found something else to fix.

Service Sch A but hard to tell
Had service A done and tires rotated. Hard to tell if oil was changed without a dip stick to look at and the tires I guess were rotated but hard to tell with the fact the tire pressure was the same in each wheel as before rotation.

Exceptional Service
I first met Christi with her friendly and engaging personality when starting to look for my next Mercedes Benz. She listened intently, understood my needs and that I was just beginning the shopping process. Three years later a CPO 2015 GLK 350 came along. During the test drive, Christi’s knowledge of Mercedes Benz was apparent as she describe the features and controls of this vehicle. Unfortunately this vehicle was not to be mine – it sold quickly and I wasn’t ready to act. Christi went to work with my best intentions in mind to help find my vehicle. Christi sent me updates of new vehicles arriving with pictures and detailed information. Through her hard work, patience, and tireless attitude, my GLK 350 crossed her desk. Christi was extremely patient and helpful throughout the process. I love my new vehicle. Without hesitation or reservation, I highly recommend Christi. I will go to her for all my future vehicle needs.
