Looks a nice mare from what I can see but not the greatest pictures.
Price wise I think she's ok. Some folks want something for nothing in the current market but I think she's a horse for a lifetime that wouldn't be outgrown IYSWIM and therefore I think the price is realistic.
Not horse of a lifetime but horse for a lifetime ie looks to be something that could turn its hoof to most disciplines and at 16'1 unlikely to be outgrown in a few years.
