odd... I've had two jeeps. An 89 Wrangler and a '92 Wrangler.
I would take the 92 hands down regardless of mileage. You don't want to mess with the carb for one thing. Other than that, from my experience, the 92 has been more solid (could have to do with previous owner, yes). I have abused it more than my 89 and it's held up better. less repairs, better mileage, smoother engine, etc. If you like the old rollbar that much you can find someone on this forum who will trade you...the newer ones are better for making custom cages out of.
