Well there's at least £20k commission on them...
Also depends on how fussed about the spec you are - Heliair or Sloanes may have some arriving that have already been spec'd and painted.
Sometimes customers cancel their order and lose their deposit so you migh be able to pick up one of those machines cheaper.
Of course the dollar has also swim in bjyers favour recently so it may still be cheaper to buy one now than one that has already been ordered and paid for.
Why don't you just ring up the dealers and ask?
