The vehicle's inline 6 engine is top notch and the transmission works very well. The problem with these Jeeps is that the small things continually break. Replacing small parts for $10-20 adds up. The electronics in the Jeep have held up for a long time; however, the wires that run through the doors tend to short out or break because of the constant opening and closing. One thing they do right is give you enough room in the engine compartment to work.
