Yeah - I noticed that when they listed the prices on nissanproduct.info. Not enough reasons to warrant the increase in price. And for a market they are not advertising, you should do all you can to bring in those purchases - not drive them away more.
I am glad I have my 2013. I would love to be able to find a individual at my dealership that can help swap my 2013 headunit for the 2014 (and potentially rims) at minimal cost. But if not - I am still happy with it.
Nissan and all other manufacturers have the problem of meeting government CAFE standards. This means trying to design all cars to get moped gas mileage so that they come out with a government dictated average for their whole line of vehicles. Xterra is not an econobox, if they sell too many it skews their CAFE average.
The EPA would have us all riding either mules or trolley cars. Who voted those people in?
