I have 2 that I trained myself. They can make really fantastic little horses that have a ton of heart, personality, and smarts. One thing I've found is that when they bond with a person, that bond is tighter than any I've experienced with any other horse in my life. Do you plan to adopt one unhandled or one that's been started through one of the training programs? If you've never trained a horse before, a mustang would not be a good place to start. Because of the heightened fight/flight instinct, they can be a real challenge if you don't really know what you're doing. However, if you have a trainer that is going to work with you, then go for whatever level horse you want
These are my 2.
goodness, 9 years old. I got him as an unhandled 3 year old stud with the intention of breaking him and selling him. Then, I fell in love and decided to keep him. He has been my trustworthy mount for 6 years of trails, ranch work, rodeos, and carrying flags in the parades. I wouldn't sell him for all the money in the world.
And this is my other, Koda, who's 8 years old. He had been adopted by another person as a yearling so he had been handled just a bit but didn't know anything. His owner had sent him to one trainer and got him back with the label "untrainable" :roll:. Anyway, I got him as a 4 year old but he ended up turned out until he was 5 because of my lack of time. When I finally got the time to get him up and get him started, it was maybe a grand total of 2 hours from the time I roped him in the pasture (because there was no pen to run him into and he would not stand to be caught) to the time I was trotting circles on him in the round pen. He has made a very nice horse but I need to find him another home because he's being neglected at my house. I simply don't have the time to ride him the way that he deserves.
This was his 3rd ride ever.
