Nismo (Nissan Motorsport) is the sports branch of Nissan. The Z-Tune designation refers to the ultimate Japanese official manufacturer. So when Nismo took care of the famous Nissan, it gave the best Japanese sports car ever created: the Nismo Z-Tune GT-R Skyline. Produced only to the tune of a few hundred units, this femme fatale is so sought after that it now costs close to a million dollars!
