I have NO idea what horses go for around there. And it really depends on his training, too. He's a pretty horse, all around. I think his confo looks pretty good. That dip in front of his whithers can indicate that he has been ridden alot with his head up and bracing against the bit, but you will be able to tell when you ride him if he has developed a habit of going this way.
My firend has a NSH and she is a lot of horse, very hot. She wants to run with a "gazelle" head all the time. She is also a bit sway backed with mutton withers, which makes her a nightmare to fit to a saddle. But she has tons of personality, is very pretty and very smart.
I will be interested in hearing what you say about thus handsome dude alfter you have had a test ride. He could be a really nice horse, but I bet he's a LOT of horse, too, but for you, that might just what you are looking for, no?
