Hi, I'm interested in getting a V35 and I have found a perfect one with Nismo body kit, 6 speed as standard. The problem with it is there is no stereobut there's speakers on the door & Brembo's. He guy told me it's a track spec model. Is it true? I can't find anything related to it. He also said the suspension is stiffer too. Anyone can share a light? spec?
