While that may be true in your area, is absolutely isn't everywhere. I've owned and sold horses while living in Westchester Cty, NY; Bucks Cty, PA; and here in SC and would never offer a trial on a horse - nor have I been offered one. I have bought and sold dozens of horses over the years in price ranges from free to $10,000.
I've allowed prospective buyers to come as many times as they feel necessary but once the horse leaves my farm, it is theirs. I have no control over the safety or horsemanship of that buyer. I have no way of knowing how they treat horses or ride them or even who will ride them. How they appear when they are looking at my horse may be entirely different from who they really are or what kind of situation they put my horse in. Accidents and neglect happen.
I say that only in case anyone feels that just because a seller doesn't want to give a trial, that there is something wrong with the horse.
