If it has the 300 cid. Ford and the C6 auto trans IMHO it is worth more than one with a manual trans, or the Perkins diesel..
Very capable machine, and useful with a blade for moving snow.. A bit heavy for the really steep and deep, but still capable. The 4 man cab is a big plus..
If you stay on trails the quad tracked trucks maybe fine. But in deep unpacked snow, my bet is the old 252 would be pulling them out...
So it depends on your useage. As for price, less than $10K, more like $8K imho. And at that price I would want to take a look at the ring and pinion gear in the differential first..
