Hello and welcome.
As you can tell from my post count, I am also new. As the author of one of the threads linked, I can give you my perspective after a few weeks of debating over the exact same thing.
As others mentioned, I would not consider a V6 from the 11'-13' models as the transmission does not do the Pentastar justice. If you are considering this MY, you need to consider the V8.
Now engine sizes aside, I have made up my mind and am going with a 14' Limited or wait and save a little more for a 14' Overland. I think the newer stereo, newer gauges, newer front end and rear end as well as transmission are all things I will appreciate more than saddle interior (my biggest reason to get an Overland). I think everytime i would see a 14', I would regret my decision if I went with a 11'-13', even if it saved me a few bucks. But I am of the opinion that all of these changes are improvements, not all share the same sentiment. I especially like the LED DRLs but need to get a Limited w/ Lux II or Overland to get em.
Good luck with you decision!
