I do not understand Mercedes dealerships refusing the car - but I got over that years ago. MOST work done on the car can be done at any local garage (sticky key, brakes, etc.) for any specialized work, just find a small shop that is known for Mercedes expertise.

Taking the car to a Chrysler dealership is the worst thing you can do. I do not know, after nine years on here, what more we can do to spread the word.

But in general, I don't take cars to dealers anyway. Once that warranty is gone, dealerships are no longer a viable option; they are tremendously dishonest (there are exceptions, but generally none operate honestly). When you start a post out with: "Hi, I'm new here, took my car to the dealer and now......" I can predict what text will follow.
