He's Houston too. MANCRUSH!!!!
Keep in mind that if you want leather/heat(in tx?)/power(2 seater?) then it comes with Bose. Nav is an upgrade from there. If you don't want Bose and plan on going with an aftermarket HU/Nav then you might want to look into getting seats after the fact. They get sold from time to time when people make their Z's into straight racecars and sometimes for other reasons.
