My Jeep is now 1 Year Old - I have not had one problem with it. The 4x4 works great and the reliability is fantastic. Fuel Economy - well Jeeps are never known for that, but overall it's not bad on gas, fill 1-2 times per week. Interior - It's not easy to reach the back seats in the 2-Door, and the Running Boards can get a bit slippery in the Rain/Winter causing hazard when reaching to get to the back.
