I had a 2005 S version Xterra for almost 9 years. The 2005 was modified somewhat (lift, real skids, Alpine head unit, and a bunch of other stuff), so the only real change going to the stock 2014 Pro-4X from the stock-ish 2005 was the e-locker and the heated seats.
In the four years I've had it, I've used the heated seats a lot more than the e-locker.
