We know of a livery where someone owed money and they blocked their wagon in with a tractor till they paid. Not a nice situation to be in and they may want to pay before the word "slips" out to other yards that they are bad payers?
My friend sells ex-racers for part of her living and she asked £2500 recently for a really lovely lad and had her hand snapped off. He had all the potential in the world to event I think his potential is worth thinking about in regard to price.
