I did some further digging and here are the results of my questioning:
• Auto Zone does not carry the Vent Visors
• Advanced Auto does not carry the Vent Visors
• Wal-Mart does not carry the Vent Visors
• Napa does not carry the Vent Visors
• JC Whitney does not carry the Vent Visors
• Nissan does not carry the Vent Visors
Other various and less well known online sources do not carry the Vent Visors.
I went so far as to check all available year models of the Leaf to see if an older model version would fit the ’13. No luck there either. I am left to assume that since this is not a high selling vehicle, the accessory making companies are not going to invest making the molds for us.
I also wanted to purchase WeatherTech all season floor mats. Same issues as above (and as mentioned by other forum members). I did have luck in this arena though with the dealership. Nissan sells their own brand of all season floor mats, which look very similar in construction and styling to the WeatherTech brand. I assume you can only order these via a Nissan dealership. They cost $100 for all four. My dealership offers a loyalty discount, which dropped the price down to $89 before tax.
From Nissan:
