I bought my 2000 WJ new. Quadra-drive V8, not dual climate control but every other goodie you can get. No problems aside from a door latch issue. By far the most reliable rig I've ever owned. I punished, it drove it daily for years, modified it and now have it as my dedicated trail rig. Love it, and know it will outlast my use for it.
One more thing, power to weight ratio the 4.7 V8 wins hands down. I've owned the 4.0 I6 and can say it is a complete toss up on reliability, gas milage benefit is nominal so why wouldn't you do the V8?
