Technically reports say that the "Nissan 370Z Nismo Roadster concept" is all new". IMHO it’s really just a convertible version of the existing Nismo 370Z. And if that being the case, it’s not a huge surprise that the concept looks production ready in no time with Nissan likely taking a production 370Z convertible and outfitting it with all the same Nismo goodies found on the Nismo 370Z coupe. Nice meeting you "Mr. New Roadster" lol.
