Spirit, it is not that it cannot be fixed. Many people don't want to or do not have the resources to spend money on a horse with issues that may take weeks or months to resolve before they can be comfortable riding them. If I was not prepared to handle the issues myself, I would discount him immediately because not only would I have to spend the money to buy the horse, but send him to a trainer or have a trainer work with him and me to resolve the issues.
Frankly, if the OP is a beginning rider (which I am assuming she is), then she has no business taking a horse that is less than saddle ready and easily manageable. No offense intended to coffeemama, of course.
