The Nissan Silvia S15 was produced in two core production models: the Spec-S and the Spec-R.
However, the rarest variants were the Autech and the Autech Varietta, with the rarest of all being the Autech Style-A model (54 units).
Nismo 400R was originally planned for a production run of 100 cars to celebrate Nissan's Le Mans racing program.
Due to its high production cost, only 44 units were ever produced.
