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.
'00 XJ - Somewhat modified
'01 Venture - high mileage, paid for, shut it
