First of all, welcome to Jeepz! Always good to have new members. You couldn't have picked a better, more friendly, more laid back, more helpful site. I know I speak for the group when I say I hope you stick around awhile.
As for your question, understand that it's hard for any of us to say with any certainty which of the Jeeps you've mentioned is a good deal, since we haven't really laid eyes on them. Any responses will be based solely upon average conditions and pricing of similar Jeeps. Pricing will also vary by geographical region. A $7000 Jeep here in Kansas might fetch as high as $11,000 on either coast. For the most part, from what you've described, the prices you've listed don't seem to be too far off the mark for the particular Jeeps you've described. I wouldn't worry too much about a Jeep with 100k miles as much as I would worry about how those 100k miles got put on it, how it was treated, how often it was serviced, etc. A well-treated Jeep engine will last a few hundred thousand miles without much in the way of repairs.
Basically, what it all boils down to is what is the Jeep worth to you? There's an obscure old adage about buying vehicles that says a vehicle is only worth as much as you are willing to pay for it.
There are a few things to watch out for when buying a Jeep or other off-road vehicle (are there really any other off-road vehicles compared to a Jeep?). Don't hesitate to crawl underneath them and get dirty checking them out. Look for large dents and scrapes in the skid plates, or bent skid plates, drive lines or other bent components under the Jeep. These are the tell-tale signs that they have been wheeled hard, and possibly abused severely. Of course, look for the obvious signs of fluid leakage from the engine, tranny,
transfer case, and differentials. Open the hood, pull the air filter out and check to see if there are signs of water being in the airbox, which could signify that the Jeep has either been submerged or driven through excessively deep water and possibly sucked water into the engine at some point. Pull back the carpet in a few places in the interior and look for rust or other signs of water damage. It's generally best to avoid Jeeps that have already been lifted, unless you know who did the work and can trust them. Many times a lifted Jeep for sale has had shoddy workmanship done on the lift, and the buyer is saddled with a ton of issues ranging from poor driveline angles to over-torqued bolts to mis-aligned components. It's almost always best to either do the mods yourself, or have them done by a reputable shop you know and trust.
These are just a few of the things to look out for when pricing a Jeep. As I said earlier, it's difficult to tell you exactly what a Jeep is worth without seeing it and comparing it to similar Jeeps in that particular geographical area, but hopefully it will give you a fair idea.
Again, Welcome to Jeepz! Keep us posted on what you do, and if you have any more questions, don't hesitate to ask, we'll all do what we can to help you out.
