The 45th Anniversary Gold Edition, built off of the GT-R Premium model, commemorates the GT-R's long heritage of world-class high performance. Featuring a special gold paint color, the limited edition model also includes a special gold-tone VIN plate located inside the engine compartment and a special commemorative plaque on the interior center console. The paint color itself is the same "Silica Brass" color that marked the 2001 Skyline GT-R M-Spec (R34 Type). Fewer than 30 of these special GT-Rs are slated for the United States market.
