What to look for, 69 cuda
Mikeee, after looking at those pics you posted, I'd be very concerned about the floor pans ... the purple-ish discoloration on that carpeting is a clear indication of water (probably from the wiper pivots). When you go to look at it, see if you can take a peek under the carpeting -- it's probably not tacked down underneath the dashboard -- and see how bad that rust is.
