What are you looking for in a horse?
Do you want a big, fast mover with lots of motion underneath you? Because this guy is it. Just playing the Devil's Advocate. Yes, he's flashy. Yes, he's pretty. But looking at that still photo of him in the canter, it appears as though it'd be quite a rush on his back in that gait.
The first trot pic looks nice. Calm and balanced. The second trot pic looks entirely different. So, ask yourself what YOU want in a horse. If you want a steady mount that's at the same pace today as he was yesterday, and the same day last month even, this guy might not be for you.
It doesn't appear as though he neckreins. Everyone in those photos is direct reining him, save for the picture at the bottom where his trot is gigantic and the girl is holding the flag. It might take a two rein hold to keep him back.
Of course, I could be completely wrong with everything. But those are the cautions (and inconsistancies) I'm getting from the pictures and definitetly something you might want to consider before you get carried away with his purchase.
I hope that your visit goes well and he turns out to be everything you wanted in him, though
He is a very pretty horse.
