370 types? (I'm a confused noob!)

Shift-Ee

Well it says in the title, this guy is one confused noob trying to make sense of the different types of 370s out there. I noticed theres the base, touring, sport, and NISMO. I've been looking into pricing of a used 370z (manual) in blue and whatnot. How come some of the tourings have the crappy brakes, and others have the nice black calipers (sport brakes?), as well as the nice 2011 style wheels. What models get the bose system as well? Can someone help me classify these? I understand the Nismo Z comes with basically everything awesome while the base comes with, well...nothing too special. Ive been looking into 2010-2011 Z's with under 30k miles. Can someone help me classify the differences between the model types of each year, and also what were the differences between the 2010 Z and the 2011 Z? Thank you so much guys!
