It all depends on what you think it is worth. I have seen 99&#039;s go for between $300-$5,000, and normally you get what you pay for. I would guess a running 99 would sell for between $2,000-$2,500. But, if this is a good straight tractor that doesn&#039;t require much work, $3,000 is probably a bargain. You have to fiqure in anything you will need to do to it, as no repairs are cheap! Hope this helps you!  Later, Andy
