Welcome to the forums
. With all the Z cars you have owned in the past, it seems like you're a Z Enthusiast. Got any pictures of your Zs?
If you like your 350Z then you'll LOVE the new 370Z. Auto - manual -- it doesn't make a slightest difference. Buy the one that you feel comfortable with. I loved those paddle shifters on auto Z btw.
The blue color is Monterey Blue. I currently own a Z with that color. I really like it.
Feel free to ask any questions you may have. Hope to see you behind your own 370Z soon.
