Looking at a 73 truck anything special to look at

Decent looking truck and I've always liked that paint scheme. Like an above poster said, check the rain gutters. They're the main culprit of rust on trucks around here. I personally think the price is a little high. I'd offer him $2500 and see what he says. I don't see many people around here jumping at that truck so I doubt it'll go quickly anyway. He brings up the whole nada guide deal which is never correct for these older vehicles. He thinks the average retail price is almost $6 grand for these trucks? Yeah right.
