While I'd like to see what the next-gen Z looks like, I'm happy with the one I have. If Nissan takes a break from them for a few years, then brings it back, I might get one then, who knows.
ATM, my next car is going to be a 2018 Cayman S, painted Nissan Monterey Blue. I'd have gotten a Cayman when I got my Z, but I couldn't find a color that would stand out from the black, white, silver and champagne colored cars on the road.
To add insult to injury, when I was shopping cars, every sales clown at any GM stealership, wouldn't let me even test drive a used Vette.
