That Ranger looks to be in a great shape and well taken care of. What makes you think it is neglected. All you can do is to let her know. If she decline to sell few times already...... let her be. No need to harass her.
We all want a great/cheap deals and that would be one amazing score if she sells but here is something else to think about. Are you willing to pay the top dollars/fair market value if she asks?
I could be way off here, but that Ranger in good condition could fetch upwards or $500 or way more. Are you willing to pay that? Even if yes.... still should not be bothering her if she decline to sell already few times.
