If you are looking at a Wrangler, go with the 4.0 I-6 engine. I had a 94 with the 4cyl, and never did warm up to it. It had plenty of power in low range, but in high gears didn't have much pulling power at all. At about 68,000 miles I decided to get rid of it before it started having more power problems, even after new plugs, wires, cap, rotor, o2 sensor, filters - the whole 9 yards.
