I am in Southern California and you could probably get close to $7000 for it around here. The summer seems to be the best time to sell too because a lot of people want jeeps. Since you have a soft top now is an especially good time.
If you want to add a little extra value to it you can easily fix the rust. Get some rust remover from a Pep Boys or www.quadratec.com
and then paint over it. I did that on my jeep and it looks good as new. It will cover it up and you'll get a higher price. Unfortunately even a little rust will discourage a lot of people. Hope this helps.
