T4R.org has a really long thread with hundreds of people posting what they paid, this plus truecar and googling the dealer holdback amount helped me get my new '16 Trail w/KDSS for the price I wanted
I was originally looking at used 5th gens but a brand new trail with KDSS was not much more money and IMO definitely worth it to be the only owner. Many or most vehicles depreciate in a way that 1-3 years old is the sweet spot, but the 5th gen has seemed to hold its value enough that buying new is a better option.
