The best feature of the Jeep is it's ability to go through anything. It has great ground clearance, a solid four wheel drive system, and room for four with plenty of gear. That being said I have been disappointed by the cheap grade hard plastic interior, weak engine performance, and white knuckle highway driving experience.
Navigation System is outstanding, exterior look, and go through anything ability
Upgraded interior with softer touch surfaces, window controls on door trim panels, More powerful engine or diesel option, improved NVH, improved back seat angle (less upright), relocate rear sub-speaker out of the cargo area.
