Dont worry I go to NEW YORK and Detroit every year (almost) and i'll get prime pictures of the Z, and all the other great cars. Cause cameras of all sorts are allowed.
But consider this, the Silvia is being sold in Japan for 20K, it's 2.L Turbo 6.1s 0-60 (250HP). The Z will be nearly 10K more, how much more performance will you get, plus how hard will Nissan work to ensure of its quality and design?
