Must be a different situation, where you are at. Every vintage pre smog (decent shape) truck,gets inflated pricing here. The agricultural folk & 4 x 4 people destroy the nice ones,way too fast around here.
All of them are in better shape the original ad posted here, and most of the ones in comparable shape are pretty close to $4k. Like I said, if someone gives more than $4k for that truck they're nuts. And if they give more than $3k they overpaid.
