I'll stick to this Z (owned since 1987) and my other Z... ZL1
I've seen the new Z in person here in Nissan's back yard at Nashville Cars and Coffee several times. I'll wait and see what the NISMO version is like, with improvements especially in the front grill/fascia area.
I just gave my 300ZX Twin Turbo to my daughter and her husband in Virginia. They drove it back just last week.
