Hi
I agree with P50 it boils down to supply and demand/and wha people want, but I would put something else into the equation it's called the AC (Andy Carter) factor, if your average guy cant find what he wants he will get a replica, so people wacthing Top Gear, will go to him to buy a replicar P50 or Trident because as P50 says the supply is ZERO, I've just looked though Andy Carters list of cars and as well as the Peel's he has a replica of the Goggo Dart, Scootacar, the Mopetta, and the Bamby.
So applying my third criterea you can buy a replica of the Bamby if you connot find reall one.
Is Bob suggesting that J C of Top Gear is buying Bamby's
