We just traded in our '08 KK for a Commander.
We had it for just over 2 years and were pleased. The skyslider gave us some grief at first, but our last TSB service silenced the wind noise for good.
We took a 3500km road trip early July and averaged 11.9 L/100 km or 20.9mph mixed driving.
We would not have traded in the Libby if we didn't want an extra row of seats.
It was my wife's jeep and I grew to love it a lot as well - I'm an XJ holdout still, but the KK grew on me for what it was used for.
I think it's a good choice for anyone looking to step up from a compact platform in the Patriot to a Mid Size Utility Vehicle. It is a far cry better than a Sante Fe or Escape.
I would own another, but my 4.0L engine won't die, and the Commander is mine in about 2 years.
I would pull the trigger on a '10 model if the price is right, and if you get the slider, you will enjoy the open roof feeling.
I'm back on my court mandated Rx. Other than the drool shorting out my keyboard, I'm here to help!
