im corius because i got two in mexico one was brown but not exactly black and went faster then the horse you get in game then there was a dirty vanilla one that didnt go so fast off road but if you got on a trail it would take secounds to were you need to go. --- OK it's a person!
you have to break a horse before you can buy the deed i think at least with the three 3 star horses. the kentucky saddler you get early in a mission with bonnie and i had to break a wild hungarian to unlock it, i have seen the american horse in the wild too but only a couple times and was unable to catch it both times and thats the one im wanting. i think you may need to be in mexico to find them though.
