Nissan 370Z Forum - Difference in years?

It sucks being a noob on a new forum, about a new car because I have no knowledge about the car, and still trying to find my way around the forum.

So with that being said, I suspect this may be common knowledge, already posted somewhere, and I'm going to be "that new guy" but ..

I was wondering if certain year Z's are different than others? Did the change something with the engine at all, differential, improve an issue with the transmission...etc etc. Seems with every car/bike I've owned, there's always that 1 year to avoid, 1 year was better than the rest, blah blah blah. Is the 370Z the same?

While I do have quite some time before I am ready to buy (waiting for my lease to end), I'd like to take this time to learn about the car so when it is time, I have a good knowledge base.

Thanks. :tup:
