Should I have avoided the 3.8L engine?
I realize that in saying this I may offend some members here which truly isn't my goal.
I've driven both extensively and the 3.6 is superior to the 3.8 in every way imaginable. All the 3.8s I've driven are complete dogs and not much better than the 4.0 engines that preceded them. I always tell people to avoid buying 3.8 JKs if they can. Sure, you can get more power out of them with a supercharger or turbo, but the 3.6 is just phenomenally better in every way. It has nearly 100 more horsepower and it shows.
