Clay, no offense, but the Rubicon is a factory off-road beast. It is completely overkill for someone who is not intending to use the setup on a regular basis. If that is what you want to do, then go for it. Otherwise, save some pennies and go with a regular 4.0 Wrangler.
That statement aside, watch for rust! Jeeps all rust in pretty much the same spots (fenders, windshield frame, tub), but I have noticed that TJs have a spot just above or below the taillights that pops up occasionally. The paint bubbling on all of the hinges is common if you spot that. The 4.0s produced on and after 2000 have a cylinder head casting number of "0331". It is not entirely uncommon for these heads to crack between cylinders 2, 3, or 4. Symptoms usually start with a mystery loss of coolant with no leaks. Not all of them crack, so don't be discouraged. Though, both my old XJ and my current TJ had cracked heads. Done correctly, the replacement cost is ~$600. It can be done for cheaper though. I can go more into that detail later if you absolutely need. Check the floor pans for rust or rot. The death wobble that Jones describes is absolutely NOT normal. It is common(ish), but there are a number of different things that can cause it. Regardless, it should be fixed. If you have any more questions then feel free to ask me. I have been a Jeep enthusiast for over twelve years now.
I know you likely will not buy the Jeep, but there ya go anyway.
