I need a reliable Mercedes mechanic in the north west Bronx area . I have a couple of classic Benzes(1969 and 1973) and don't want to waste any time. I heard about Wolfgangs in Tenafly N.J. but also heard he is very expensive. Has anyone used his shop that would like to comment? I heard about a place called Luigi's in Nanuet , N.Y. too...Of course I would like a place close to the north west Bronx but will travel for a good shop. Any help is appreciated.
