I would be concerned about how deep she gets to fences and that she doesn't use her front end at all (knees, legs, head, neck, etc) over the fence. She does not appear very scopey and appears to lack a lot of basic flat work and has very little if any adjustability. For that price I would definitely pass. Buy something unstarted and cheaper and find a knowledgeable trainer to start it correctly. That would be a better use of your $5500 IMHO.
