You know what fuck you asshole I'm answering anyway. Lucky I like you.
The 6cyl is probably the most solid 6cyl ever made. When they do break, parts are easy to come by and repairs are easy to do. Don't be put off by oil leaks if it has more than 80k on it, it's kind of normal. They have issues, but they are issues that are common to any Jeep with that motor so they are easily identified.
The Wrangler is good on gas for what it is, and you can change the gears in the rear to squeeze out a little more if you want, depending on which gears yours comes with to start (in other words, if there is room for improvement or if it is already the best it will be). Manual is better for gas mileage but I'm sure you know that. The auto trans in the Wrangler is a bullet, no worries about it living a long time.
Soft tops should be avoided. Buying a soft top for a hard top is cheaper then buying a used or new hard top to go on the soft top. Soft tops are noisy and suck in the winter. They also rip from ice on occasion.
Keep in mind that Wranglers are at a higher risk for rollover, they need to be driven more carefully.
Keep in mind people love to screw with Wranglers. You are going to do best with a stock used wrangler that nobody has messed with.
Look underneath. Most people who are going to take them off road are too lazy in the winter to wash the underside well before selling it. You may see clumps of mud, grass, sticks, rope, etc. That gives you some idea of what to look out for, and a negotiating point.
Check the wheel wells, door jams, floor boards, exhaust, and under body for rust.
That's all I can think of right off. You already said the biggest part, they hold their value. You can always resell it EASY.
