I really like my 07 Commander Ltd with the Hemi and QDII. I agree with everything Polar said above. I like the comfortable seats, creature comforts in the Limited, reserve power of Hemi (or you could go 4.7L V8), trailer towing capacity and I like the looks and the peace of mind of curtain side airbags and a solid vehicle.
I rarely use the 3rd row seats but nice to have on ocassion. So my third row is folded down most of the time.
I might be luckier than some. I have 60,000 miles and no problems.
I recommend you review the Jeep official site for how the various 4x4 systems work on the Commander to help you choose what you prefer and what you might settle for. http://www.jeep.com/en/4x4/how_systems_work/
The Commander can come 4x2 so don't get it by mistake as one or two people have.
The 4x4 flavors are QuadraTrac I (fulltime 4wd, no 4LO); QuadraTrac II (fulltime 4wd, with selectable 4LO) and QuadraDrive II (fulltime 4wd with selectable 4LO and has electronic limited slip differentials front and rear, which will go from free spin to fully locked and anything in between automatically).
I have the QD II and it is awesome. One thing, with these vehicles, be sure you run the same size, brand, model, etc tires on all 4 wheels including the spare so you do not ruin the transfer case and diffs.
If you put on a lift with bigger tires, note that some larger tires will not fit in the normal spare tire location under the vehicle and you will need to store it elsewhere.
Good luck and let us know what you find as you shop. We like to share our opinions whether you want them or not.
