I wanted the new rounded window with no cover. Wound up with a 2016 with the old flat covered window. While I say the newer one
does look much sleeker, I am thinking I am glad we got the old flat style.
What would have been a deal-breaker was the flat, non-rounded shower. Supposedly they didn't change to the round showers till 2017, and all the 2016's I have seen (live or in pictures) had the flat shower. But lo and behold, my 2016 had the round shower
Those few inches makes the difference between being "tight but usable" or being "an unusable waste of space"
