In general, would an Appaloosa make a good English/jumping horse?

I'm looking at a horse to buy right now, he's a cute 8 y/o appaloosa gelding. I would be using him to show (local, very low key shows) in english show jumping. The description of him online says he's been trained in english and knows how to jump, and his picture is of him jumping. Do appaloosas make good jumping horses?
