Thanks for all of the members useful replies. Yesterday I became a member of ALLDATA DIY and I've already found things about my car that are very useful in my quest to learn how to do the work and better my first Mercedes. Another thing, and I am guessing that most everyone is going to agree with me. "If you want something done right, you might as well do it yourself." This might not be true all the time, but I think is true most of the time. In the short time that I've visiting, reading and requesting info from this site I've learn a whole bunch from everyone's helpful advices and inputs. MercedesShop.com is the best place to get the right information. Thank You Kindly, PEP
