When Does the S15 Silvia Turn 25 Years Old?
The 1999 Nissan Silvia S15 is 25 years old starting in January 2024. Once it turns 25 years old, it will be exempt from NHTSA requirements, and legal to import to the USA.
There were three different varients of the S15, The Spec-R, the Spec-S, and the Silvia Varietta. The S15 is an evolution of the S13, and S14 Nissans. They were available with 5 and 6 speed manual transmissions, and automatics. Also normally aspirated and turbo versions of the SR20.
