$100000 is lots of money. Most of people don't have horses nearly close in price, so asking if I'd sell my cheap one or not is a moot point, because I'm realistic and know I'll NEVER be offered such a price for either of my mares.
However those people who can afford pricey horses more often than not look at it as a business (which is very understandable, because expensive show horses require lots of investment into training, boarding, tack, etc.). So I can perfectly see when someone sells $80K horse for $100K to buy a different one with better potential.
P.S. I'm not talking about situation when horse is on market and someone is crazy enough to offer a crazy price. So Duffy, if someone offers you $100K don't turn it down! :)
