These are fantastic. Pre-facelift ('96 or prior) ones are the best, at least in my eyes, although some of the upgrades the later cars received did improve a few things - but the simpler styling of the earlier ones is more desirable. They seem to last better as well.
Don't expect better than 20mpg, unless you're very lucky, but it's unlikely that's ever a problem for most.
They take the mileage very well provided they're cared for (fluid and filter changes, for both engine and trans, and coolant). Common failure points are rust, sagging rear springs (which can then cause differential input shaft bearing problems) and worn steering components. A good one should feel taught, lively, accurate (comparatively) and quite swift!
Loads of them have been just run into the ground, so finding a good one can take time. The difference between a good and a tired one is blinding though.
Insanely tough things. I'd want lower mileage for the money, but that one does look quite clean at a glance.
Any questions, just ask. Had three, would love to have one back (this one in particular).
Wasn't much I didn't do with that. Very fond memories of pushing a completely seized Omega estate to the top of a twin-deck transporter. Quite challenging to stay on the ramps, as you couldn't see them, but the Jeep behaved like there was nothing in front of it!
