One of the cool things about the Z car is it's history. I like cars that have some soul... cars that actually came from somewhere. Z, Mustang, Corvette, 911, etc... all these cars started somewhere and have evolved over the years in their own special ways.
It's just cool to hop behind the wheel and think "Man, I could be sitting right here back in 1953/1955/1964.5/1969 when this was just getting started..."
I get all nostalgic and emo.
