The dealership in Orlando is not the best place to have this done. Email me using the button at the bottom of this post and I'll put you in touch will my uncle. He lives in Longwood, is the current president of the Central Florida section of the Mercedes Club of America, and has owned 20 Mercedes Diesels. He'll point you in the right direction.
