I also found him easy to like. He looks like he would be very good out on the trails and in the fields but I can't help but think that if he was used extensively in things like roping, competitive reining, etc., he would not not stand up physically (this comment is based on what I see in his conformation and way of going; I wonder if a vet would say the same thing?).
You should take a look at him. When you do, see if you can get the owners to set up situations close to what you might be planning to do with him (eg, walk in the ditches with a quad or truck coming up and passing him). Good luck and I hope I'll see you posting a photo of him as a new addition to your barn in the near future.
