The 2011 - 2017 mats are different from the 2018+ mats, especially on the passenger side, IIRC. Also IIRC, Weathertech didn't do a great job with the passenger side mat for the Gen II Leaf, and it isn't a perfect fit. On a related note, AFAIK nobody yet makes a seat cover that perfectly fits (or is easy to install on) the power driver's side seat that is part of the Gen II Tech Package.

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.
