I second what MeggPotr said and add:
A horse can love you from the ground, and be a nightmare from saddle, and vice versa, a horse can be perfect from saddle and impossible to handle without a stud chain and 3 helpers.
Ground and saddle are different things.
Oh, and your horse doesn't actually know that it's "wrong" to bite, kick, buck, rear, etc etc. Humans (trainers, handlers, riders) can teach the horse what is considered ok or not ok, but it's beyond any horsey reasoning that if he bucks hard you might fall and break a bone. Horses don't even know that you have bones that can break.
So if a horse misbehaves, correct it, but don't take it personally. A horse doesn't misbehave because he doesn't love you, and a horse doesn't behave because he loves you. If a horse does something majorly wrong (hard bit, kick, rear) he doesn't do it because he wants to deliberately betray your trust.
Training, training, training is the only thing that makes the difference.
Another thing that you might consider: how much do you care that your horse loves touch, grooming, is cuddly and all? Because if it something that is important to you, look for a horse that is cuddly from the beginning.
Don't hope that a horse who doesn't like much touching, will become all touch-friendly after you establish a relationship. Some horses just don't appreciate it. They can like you and trust you and be a dream to ride, and still not show any pleasure to be groomed.
Don't buy a horse who wants minimal contact, if part of your horse-owning dreams
includes a friendly, dog-like, cuddly horse.
Those who like to be petted, will show it very soon, most likely from the first time you see them.
