I bought my Z new but you can easliy find a low mile Z used. A used Z with fairly low miles usually means it was driven less and probably well cared for. Also if you want a nissan extended warranty for the car can be purchased fairly cheap. So dealer Nissan certifided is a meh for the most part and a used car inspection 50ish dollars. Cheap nissan warranties can be purchased through Nissan of Santa Rosa, CA.
