I had a CJ5 back in the 80's and have always missed that Jeep. Fast forward to 2005 and I have a new Rubicon, 6 months now. The Rubicon is light years ahead of my '76 CJ but still has the same level of fun. I have a smile on my face every time I get behind the wheel. This baby can climb! I live in the desert in Southern California and we are always taking this Rubi on the mountain and desert trails. Trails I wouldn't hike up on foot, no problem for the Rubicon. The top is off 90% of the time here in the desert, it's great! Around town we have a blast as the Rubi always gets the looks. I love the rough ride and feeling the road. Cushy cars you drive with one finger are not for me.
The Rubicons heavy duty upgrades, the A/C works great when the temps hit 110+, sound system, all of it!
None I can think of except for the gas mileage but it is what it is, a Jeep.
