Just bought an '85 245 DL for $470, a project car for the eventual use of my son.
Engine, transmission, suspension, body are sound, lots of niggling problems from benign neglect.
Car was not driven for a few years until recently.
Has third row seat: when lifted seat up, found water pooled underneath.
I can see no source / cause of leakeage to allow water to enter; could it somehow have seeped in through a weak rear door / tailgate seal?
Headliner looks like new, no stain or moisture.
Baffled...
