Mercedes has told me they cannot be of any further assistance (they fixed a few rust spots late last year). I'm not sure if I should sell (I really, really don't want to) or keep it. If I do keep it, I need to figure out what I can do to hopefully stop this problem for good.
I lived in Boston and my 95 E420 NEVER saw wet road salt, had a winter car for snow. Despite that, it kept rusting and I attribute it to the humid air and inevitable dry salt dust from driving around when the roads were finally dry after snow storms.
Really sorry to hear and it is frustrating. I am not sure there's a way to rust proof it aside from potentially not driving it at all as soon the snow falls until May timeframe.
Maybe others with more experience can chime in.
If I move back to Boston, I think I would be storing the G in winter until summer...
