Well, I have a 61 half ton that I paid $4500 for. It too has no rust (or very little) but it has one slight dent. Mine's mostly original however, including the engine and transmission. No suspension upgrades or anything. I bought it in Washington and had it shipped home to Alberta Canada. If he's really being honest and it actually does have "no rust or dents" then to me, $1800 is a really good deal. Be careful though. My first truck (also a 61 Chevy) I was told by the owner over the phone that it had very little rust, and only a few dents, and was "really solid". I ended up buying it, and after owning it for a year, found out it was solid alright, solid Bondo. There were holes in the floor, and the cab mounts and floor supports were so badly rotted out that the cab shook when i went over large bumps. And I paid alot more than $1800 for that truck (then again, I bought it here in Canada, old cars seem to be pricier here.) Check it out in person. Get right underneath it, check the floor, the cab supports, rocker panels, everything. If the owner doesnt mind, run a magnet over the body to see if theres any body filler, check especially the lower parts of the front fenders and doors, and the rockers. Take it for a drive too if you can.
