Thanks Gilly, for the help. I did buy it--for $500! I'll put it up on the stands tomorrow and change out the fuel filter and if possible without dropping it, drain the gas tank of the varnish smelling stuff inside. When I popped the tank cap, it was still holding a good bit of pressure (a good sign I guess).
I'll pull the plugs, disconnect the fuel pump and coil and see if it turns over without a gush of coolant or nasty noises.
Where do you get the fuel system additive you referred to?
And, is there an on-line salvage yard specializing in MB for the stuff like plastic seat hinge covers, fusebox covers, etc.?
