Well, I guess they can't all be good, sorry you had bad luck fishaholic, but a 4.0 Cherokee is one I would recommend. the 4.0 is one of the most reliable long lived engines made.
My son had a regular Cherokee 4.0 (stick) and had great luck with it, and now has a Grand Cherokee 4.0 (automatic), and this is a real nice ride.
Great on the beach, both of them.
