I kind of figured that she was older, given that you asked us to guess her age...tehehe. My mom has an Arab that is the same age as her, and looks fantastic as well...more like a plump 15 year old than an horse in his 20's. Haha.
I am not a fan of her super high withers, and her shoulder is a bit steep, and her rear legs aren't as angular as I would like, but that said, her faults are nothing that should hinder her in anyway as a trail horse. She's got a beautiful face, and a lovely kind eye...I say steal her up, before I do!!! haha
