IMO, if bought for cheap enough, the body alone would be worth it to use for remounting on a new(er) chassis. Then, sell the old chassis. Carpenters, contracters, farmers, etc might be interested in it for cheap enough.
nope, sure can't. We have an old silverado for a brush truck, we got it new in 1988. Still runs and drives to this day. It's been wrecked 3 times, transmission rebuilt once, and has had regular maint. done.
