Second one not too bad. No holes or huge amounts of rust. They did kind of speed past the back end a little more as they went around the vehicle in the video.
The spare and the hitch are a little crusty, but the main rails and stuff did not look terrible. Be aware that Z71 plastic trim panels over the rockers and wheel wells can hide a lot of things.
First one with the still photos above is a MUCH cleaner example, though! I would pick the one in posts 16 &17, if it was reasonably priced.
Reasonable is a relative term and market driven.
My 04 had more rust than the 05 you have in the video on post #18 above. Last October, it was $6,500 with 180k+ miles and "weight reduced" aerated rocker panels. This was a hot market in New England for anything that was still able to stay in one piece and pass RMV safety inspections.
$6,500 in other markets would get something in better condition in terms of rust.
Under $10k for something with no rust would probably be about right for my neck of the woods.
