Bloodlines only mean something to the buyer, and of course the sellers pocketbook. If she does the job well, then worth it; if not, then it's not. I recommend test drives, blind visits (meaning don't tell owner you're popping by or at least give them minimal heads up. This will show you if she is able to be caught, her attitude, etc.). Also for big money a health inspection would be wise. Not that it is bad to not trust people but really, in this horse economy there are plenty of good horses out there for reasonable costs. And drugging happens, as well as working the poo out of them prior to buyer's arrival, and other dandy little tricks. Look around a lot. Think of it as buying a car. Most likely you wouldn't buy the first one you see on the lot and certainly not before taking it for a spin around the block.
Nice color but conformation wise, definately not the greatest though that means little if her temperment is good, and she is easy to handle. Would not ever consider breeding this one because of conformation, and horse overpopulation.
