I purchased a 2016. I could have gotten a 2015 for a LOT less, especially with the $2000 rebate, but none of my local dealers, I tried seven different ones, were able to get a 2015 for me.with the options I wanted. I would have had to fly to the Idaho panhandle or Pennsylvania and drive it home in order to get one. Plus, I REALLY didn't like the shifter in the 2015s. It seemed like there were a few other minor, mostly cosmetic and software, changes in the 2016 that induced me to go with the newer model.
As far as MSRP, here is my window sticker. I paid $52,011 without a trade-in.
Note it still shows 5 year/100,000 mile powertrain warranty. My dealer said Jeep was dropping it to 60,000, but I think I can hold them to the 100,000 based on this document.
One thing I'm running into is a lack of after market accessories for the 2016. For example, HuskyLiners told me the floor pan in the 2016 changed, and they are retooling to produce Weatherbeater and X-Act products (WeatherTech's don't fit quite right, either). Mopar says their rock rails don't fit the 2015 or 2016. With 2016 being a compressed model year, I wonder if many companies will even bother making custom fit accessories or just wait for the 2017.
