I've replaced the sunroof gasket. MB revised the gasket from the adjustable felt type oiginally installed to a nice softer rubber unit that is not adjustable but rather offers a great deal of cushion to satisfy any large gaps and will compress nicely to smaller ones.

BUT I've still found water on the floor on the passenger side. Doing some more investigation around the windshield, as M.B.DOC suggested, I've popped the fuse/relay cover on the passenger floor and checked up high and find the insulation towards the firewall is wet. Water is coming from above - now the questions remains...from where???

Any suggestions? Anyone have such an experience? Tks
