Once you factor in all the individual options particular to a given truck e.g.
radio delete, strange color, posi, 6cyl, Hydro brake booster etc, it could quite possibly be rare.
However, don't confuse "rare" with desirable. I see that all the time on craigslist. Fellow has a run of the mill everyday work truck, and thinks he has a Gullwing Mercedes on his hands... and is priced as such.
