I had to convert my Chevy mechanic. He loves working on the cars. Really isn't a lot of difference until you get into the eletronics. Then, it is a call to Rudy for help. Usually with his advise we are able to work thru it. Once in awhile though, it is a trip up to Chicago to see the Rudy... which is fun in itself... You have to find a mechanic willing to learn.... or an old MB mechanic who has went independant...
