Sounds like you are happy with the deal, so get it running and safe, then enjoy the hell out it. Interior looks pretty good and is probably worth a few $$ if you end up parting it out.
Look all in the cowl REAL good because that's where those cars are bad about rusting out. Open the doors and look forward of the hinges in the area forward of the firewall and under the cowl. Also look as good as you can into the cowl vents and look under the dash at the inside part of the cowl and around the corners where the cowl and the kick panel frame come together. If it's rusted out in any of the cowl area, I'd get it running and driving good and flip hell out of it.
