Ah, the old adage " if it sounds too good to be true.....it isn't"
I "ate" a few PPI's in my search for my tt.
Makes sense to generally warn the community that a car has serious issues.
Then, if some want to take the plunge anyway, I think a PM, as you've done, and generosity with the other party ( hey, we're all friends here) wrt you PPI sounds reasonable.
Good luck with you search Dave.
