I just picked up a 2020 370z Sport Coupe yesterday.
A funny story behind ordering it, is that they ordered a roadster by mistake and had to place a second order for my car. They now have a 2020 roadster sitting on there lot. I spoke to the salesman and he confirmed the vin says it is "L" (2020). The article seems tp make it sound like they are not offering it for the 2020 model year. I can confirm without a doubt that they are. I saw it with my own eyes!
Also, they have it listed on the Canadian Nissan website.
I told the salesman he has quite the handy sales pitch available to him now!
"Buy the very last roadster version of the 370z. It is now a collectors item"
