Apart from seeing the 350z being described as a giant StreetKa I think it's gotten off pretty lightly around here.
Not sure on the original list price, but if the stripes are OEM then they're not cheap, and the lights are pricey too.
The all round tints may be a concern as ANY tints or film ahead of the b-pillars is against regulations/the law. Not sure how that works on when you buy them on a used car though, so might be worth looking into.
