Yeah, the Z is a serious cousumer/enthusiast car. Get it only if your heart is ABSOLUTELY set on it.
As much as I don't like when people say it, the 370Z is starting to age. However the upgrades made to that big-body Maxima and the well-reviewed Altima would give you a more practical car when it comes to inner city travel, taking your friend(s) and family places, carrying luggage/cargo, carpooling, etc.
My first car was the 2007 Mitsubishi Galant, and man I used to put half my life in that dang thing. I miss the cabin space and gas mileage.
