Very low price. Check the door bottoms and rocker panels for rust bubbles along the seams. Check the rear frame rails, especially right rear wheelwell just above the frame. Check the metal around the rear side windows for rot, rust stains and other suggestions of future work.
Cargo area plastic is irreplaceable - but GM plastic panels can can be made decent with careful application of truck bedliner over a chalky surface if not crumbly all the way through.
On the other hand, a clean title on a (mostly) complete car for $600 may be worth it alone. The hard part is estimating the total future cost of fixing the holes and replacing missing parts. If you are outside emissions land, that makes things easier. Where will you park it until you can dig in and see what you bought?
