He looks like an awesome horse!
Personally, I wouldn't buy him, just because I'm WAY too short to sit comfortably on him, plus he looks like he has fun jumping and I'm more of a dressage girl myself. I'm also at the point where I can buy a horse that requires more training, and he looks like he's made.
If the time does come, you'll definitely be able to sell him at whatever price range you decide on. He will be the perfect horse for many people. Good job with him!
