As I write this the 4.0L 6cyl has been retired and the new Wranglers now have a minivan motor.(sad day) As you can tell from the first sentence I love the old 4.0/6cyl. The 4.0 and 5spd manual is the most desirable stock engine/tranny combo if you are shopping for a Wrangler YJ from 91- 95. This is a reliable vehicle now with 133,000 on the clock all I have done is replaced a rusted/leak radiator and water pump. Jeeps do perform best with regular preventitive maintence. (plugs, wires, oil-changes in engine, diffs, transfer case & axles) The ride is rough which should be expected and learn to love it. If ride quality is your concern I would recommend going straight to a TJ (97- 06)or new JK
I have my Wrangler as a toy, not a daily driver but whenever the weather is nice, it's my daily driver. The 4 cylinder gets around great in town, slow on the highway but it wasn't made for highway. I have a Rampage bowless soft top that's really nice. A 90's jeep is cheaper than a new 4 wheeler and a lot more fun! Aftermarket parts and modifications are never ending, you can do anything you want to a jeep(if you have the money).
I bought my Wrangler brand spank'n new. I wanted it so bad, when the dealership called me to say my order was in, I made my girlfriend take me up there to look at it all wrapped up! The Jeep Wrangler/CJ is the only vehicle that makes me get excited like some silly kid. I've done some off-roading, but nothing extreme. I've NEVER been stuck off-road, nor in the snow. It's been a pleasure to drive daily for the past 13 years. It's not perfect, by any means, but something I've cherished. Getting almost 170,000 miles on it now, the 4.0 inline 6 is tickidy, but keeps on going. From talking to others, this engine is good for 250,000 or better. And you thought only Hondas got that kinda life.
I have had my Jeep since day 1, reliable tough rugged vehicle. This year's Wrangler is probably the best of all time, with modern styling and heavy duty construction. Never a major problem, not even a flat tire. I give it regular maintenance and it keeps on going. Now that the Jeep is 11 years old, it is equipped with every high-end accessory known to man for this Jeep, except the stock engine & transmission. It now sits equipped with and Old Man Emu Suspension, and all the ARB equipment from bull bar to lockers. When it snows is when we have most fun! NYC potholes, I laugh and spit at! The only other vehicle I would switch to is a Rubicon. A new beginning!
