I've had a couple of bad experiences with them. I'm not trying to put you off, if you think that this horse is good for you then go ahead and get him, you're far luckier than i am having an opportunity to get your own horse as my parents would never let me have one. But the worst time i had with an arab was when i was cantering on a circle with a chestnut mare. She was very pretty, but very spirited. She spooked at something on the floor, it might have been a sparrow but i didn't have time to see because she bolted and then stopped infront of the brick arena wall and i was flung headfirst over her head. If i hadn't have turned slightly so i hit the wall on my side, the impact head on would have likely broken my neck, and i would probably be in a wheelchair or even possibly in my grave. Fortunately, i suffered nothing more than being instantly winded, having a very sore chest for weeks and a complete loss of confidence. But i've gone back to riding, i must be mad . In my experience, i've just found them rather unpredictable and can be strong willed and high spirited, but perhaps i was just unlucky with them. As i've said, if you really like him then he's probably fine. But just be careful, some horse sellers sell horses which are not what they say they are. When you see him, ask to watch him being led, having his hoves picked up, tacked up and ridden by someone else before you try yourself. If he doesn't seem quite right, then just be careful
