I have owned 4 jeeps and this one may be my last. Terrible engine. The 4.0 L is a more responsive, more powerful and yes stronger engine than the 3.8 L. I don't care what the numbers say. A stock 4.0 Jeep with 33" tires, lights, brush guard and only a k&n filter, absolutely walks away from the new 3.8l on road and off. Did mention the 4.0l has 140,000 miles on it? Jeep really blew this one. Buy the way the 4.0l Jeep is mine also, so it is a good comparison.
looks and suspension
Engine. Engine. Engine. And when you get that right, transmission!
