Well you should be able to get at least $5k for a great condition, bone stock VX with 127K. IMO, I would part out the goodies if you can't get at least $6K+ selling it privately and if you're not in a rush, price it at $7k and go from there. Also, you might consider buying an EMPI halfshaft for $70 and replacing it yourself. That should boost the selling value.
I looked at Commanders a couple years ago when I was replacing my car. I liked the price, size & V8 the Commander had but I heard that they have a ton of issues. I researched a bit on the Jeep forums.
