Good day MBWorld, I just got my 2009 c300 back from the dealership after they performed a "Service B"... Before I turned in the car to them, I included a list of concerns regarding weird noises heared inside the car when its running... I believe that some of the noises came from the doors and panels (probably even on the mechanisms inside the door) to mention some... But then after 4 working days given to them as per dealerships' service department request, 90% of my concerns were considered "normal" for them...

including the loose side mirror housings that annoyingly vibrates when ever the doors are closed with ease...
Anyway, since I've given up on the dealership, is there any shops that are recommended with in Southern California (with in LA County)? Will the repairs void the warranty?
Thanks,
James
