It's been awhile since I drove a 12+ but I can say that even though the 07-11 is underpowered, the 12+ isn't going to wow you unless you like to live high in the rev range. It's not a low range torque monster or anything. It you drive it normally, you will probably never notice the power difference. Now when you floor it, the 12+ will leave the older ones in the dust. But a Jeep isn't a race car, after all.

Good point about the automatic. Mine is a manual and there is no way I would buy an auto 3.8
