Ya I think 2 port is still used in Europe that's why they still have the 330 whatever stock power 2020 had. 2020 honestly isn't that slow either. Tune, downpipe, and exhaust for sound and it's just fine.
Past Nismo Z cars weren't exactly hard to get. As long as no production issue, who ever wants one will eventually get one.
The color is from the the Nismo R35, not really a copy if the color was used before on the 2022 model.
