Kelley Blue Book doesn’t do trucks, and when I say trucks, I mean I’m looking for what a used 1998 Chevy Tiltmaster W-4 with 70000+ miles would be worth. I found a site a few years ago which had some used trucks prices, but that seems to have disappeared or fallen off Google’s registry. Some other resources like trucks.com require a payment to get a pricing. I’d settle for a list of trucks of that model in various states of decay and their selling prices, I just need something to compare it to
You could search eBay current and past auctions. Auctions with bids of course, ones without bids won’t be that relevant.
Or simply a Google search (limited to the last couple years or so).
The only real guide to used vehicles is the NADA one. KBB and such are just used to confuse buyers. The dealers use NADA.
