This is more of a question for yourself. Can you handle not fitting bigger things into your car/not dragging around the children. The Z can handle a lot of stuff in certain situations. I fit myself and three other people in my car when my friends needed someone to come get them from the club. If you cannot handle having limited space and still want something sporty check out the Mustang or Evo, I will not mention that god forsaken chevy :/
Me personally I love having only two seats, usually don't have to worry about your car becoming a taxi
