I used to take my Mercedes C class AMG, to the dealership for everything, but then I found German Car Specialists and have never gone back. The Dealership told me I needed to replace my transmission module which costs the same as replacing the whole tranny. So I found "GCS" and they just replaced a missing transmission fluid plug and it's been running better and that was 40K miles ago! Not only is it way more affordable, but you get the same excellent treatment, honest assessments and they make it so easy! I am a Mercedes Driver for life, and now I'm a German Car Specialists customer for life!
