However, I found this one on ebay just as close to me....

Nissan 370Z We Finance | eBay

This is quite a drop in value in less than a year!
It also has NAV....unsure but do all NISMOs have NAV ??

Would I be crazy not to save 7k and get NAV also by buying the used one?

What would you do?

Is this normal? Such a price drop in less than year? Would I be crazy to buy a brand new one for
