I knew you would want to really let this one sit on your palate for awhile since I was hanging on the phone for a good twenty seconds with the service advisor as I contemplated the meaning of "crystallization" of the metal...Would Mercedes, which puts out a vehicle that is a world standard have metal parts that "crystallize" and fracture under extreme heat??? and exactly what is extreme heat? I dont know at this point Haasman, but I think in a way the dealer has won because I just want my car back now. I am seriously considering putting my wagon on the market.
