Here's two that I'm kind of surprised are still for sale. They've both got a pretty stiff price on them, but one you probably couldn't build cheaper and the other is pretty rare. If they were American trucks I'd expect them to be a lot cheaper, but up here there's not many good trucks to pick from.
First one, a 1981 GMC with a Duramax. This would be in my driveway right now if I had the room, but I'm already full with one truck in overflow storage too.

Second one, a one owner 1980 GMC Street Coupe. I'm not much for stepsides, but this looks pretty spiffy. I'm not too sure about the date on the picture, if that's accurate or if it's just that the guy didn't change the date on his camera. I'm not down with the tailgate mural either but I'm sure a person could overlook that.
