I think the point is the history of the helicopter and the fact it was in a James Bond film amongst others (hence the asking price).
Anyone who thinks that has anything to do with the value really is bonkers. Evidently aircraft buyers are somewhat more rooted on terra-firma than their car-fancying colleagues on this score. (Tho the car mentioned is a globally recognised icon, hardly the same to be said of the Hiller)
And why "imfamously" flown? I know it was a seriously crap movie, but condemning it to imfamy is a bit harsh - it was only a prop after all.
What an utterly ludicrous price to expect for an ancient Hiller!
