1993 c1500 6.2 5 speed price?

[Timber]

I have a 1993 gmc c1500, 6.2 diesel, 5 speed, rubber interior, cruise (doesn't work) factory air, power everything.
319,*** km

The guy I bought it from said it was worth something? I don't know. I'm new to the gmt 400 world, don't know a whole lot about 'em. Just looking to get a price range in case I want to get rid of it.

I'm Timber btw
