Don't expect anything show quality. Don't over anticipate.
They are beautiful, hardy animals. They are quite a bit of work, for "obvious" reasons. Every Mustang I have dealt with has been wonderful. They are beautiful in their own way. Hardy, hardy, hardy. They are smaller horses, but great.
I use to ride with people who sold all their Gaited and pedigreed horses, and only kept a few Mustangs. It was all they would ride or keep after that. They loved them and bragged about them all the time.
They are great for the games. At the wagon trains I went to, the Mustangs were among the top to place in the games. Especially the potato race and phone book race, etc. Anything that does well with a small, agile, enduring horse was pretty much dominated by the Mustangs.
I have heard that the stallions are quite tempermental. Which makes sense, since they were born doing whatever they want. LOL. Just have to keep in mind where they come from.
