Of course it is, Japan is the only place that's had a GT-R for that long.
While previous years have seen gains in power, Nissan said that it spent a lot of time really dialing in the suspension and tires for the 2015 model year of the GT-R. To celebrate that, and the 45 years since the debut of the first Skyline GT-R, there will be an anniversary edition, of which Nissan will build just 45 units, selling them only in Japan. It will be mechanically identical but will have Silica Brass paint, seen only once before.
This was the color of the 2001 R34 Skyline GT-R M-Spec, a special edition which Nissan sold just 250 of, and only in Japan. The GT-R 45th Anniversary Edition will carry a price tag of 10,787,040 Yen (around $91,500).
