The first post is 4 years old, but I dug it up again now as the topic popped up again and the old infos are still useful - as are my requirements are approximately the same. Married, 3 kids, 3 cats, 3 hamsters, 2 mice, 1 mother-in-law, home loan, full catastrophe... 
So 2 seater is out, but otherwise nothing against the 370Z other than that I am 41 years old. It would also have to be a GTR to fit the kids into the back seats. Unfortunately still, anything which looks like that is a Subaru in the eyes of the missus, so blacklisted.
What do you think of the Korean cars, just out of curiosity?
Cheers,
Julius
