The only thing that gives a horse value is the buyer.
For example, me.
-papers don't matter to me.
-color doesn't matter to me.
-jumping doesn't matter to me.
-speed doesn't matter to me.
I need that 18 yo nag that will get me where I need to go and put up with my kid's crap and might be willing to carry a cold saddle bag full of brew.
I would maybe pay, shoot, I don't know what I'd pay..but the point is that your nag is my gem and vice versa.
