It all depends on just what you want.
I personally didn't think that the power steering or the diff lock were that big of a deal on the 2016's when I started looking. If you like the 17's and can wait until after the first of the year dealers will drop the price on them to get rid of them. Where I usually ride I could care less what the wheels look like and actually prefer steel rims over aluminum ones. A steel rim you can beat back into shape after hitting a rock, aluminum ones just crack or a piece breaks off of them.
