That brings up a good point about oil changes and mercedes. Can mercedes honor the warranty i purchased through Chrysler, since they are all in the same? I am getting such terrible service from my chrysler dealership. The last time they had it over 4 weeks and then i picked it up to discovered they scratched the interior all up during the work and they dented the outside drivers door. I'm very upset the way they didn't take care of my car. I have written the General Manager and have yet to hear back from him to discuss my displeasure.
