I actually have absolutely nothing helpful to add here.
Many years ago I rode for a stable that had a 4th level dressage horse who was a TB/Appy and marked very much like this one, but a shade or two darker. He was cross trained in some XC too, but I was never much into jumping jumps that didn't fall over when I fell off and crashed into them.
Anyway, hands down one of the best horses I ever rode (there have been many for me) and to this day still one of my all time favorites.
I haven't read your previous horse search posts, sorry.
What dicipline is this horse and what state is she in? You know... on the off chance she is not the right one for you.
She can come live with me! :P
