Yes, because if he's around 12.2 hands, and three years old, there definitely should have been adults sitting on him for the last two years. And if you aren't serious enough to train this pony, why are you interested in trading for a mare. (I'm guessing to breed it, since they're also selling a mini stud). There's another ad on there for a 3/4 horse. Am I missing something? 1/4 pony maybe? 1/4 lemur? Who knows.
