I honestly do not think so, they do not mention much about him, but further more the horse has not been ridden for 2 years, while they say he halters good and leads good, why hasn't he been ridden in 2 years, it is obvious they must have had issues with him they had him for one year but not ridden in two....
I wouldn't pay more then 1000 for him maybe 1500 pushing it, cause of all the time and retraining he will likely need.
