Depends on how gullible people are. I was on a sleepy hollow RAF camp, and through some sort of arrangement way above our level, an officer had bought two retired ones, but kept them in our (Army) hangar. They were in perfect nick, and still had the mil plates on them. As we were only a single troop amidst hundreds of crabs, we had our own stores, MT etc. So it was pretty simple to raise a wks tkt for them, and go round to the POL point. Then rag them round the airfield and SPTA
Performance wasn't too bad, but the steering was bloody awful.
I use to fuel them up from a Bedford in Batus (endless jerrycan filling) then later on they gave me an 8 tonner (even more jerrycans!).
That was in 1995 with 2gp safety staff. The social life was cracking though!
