Looking into Purchasing a 370z Nismo

K5_GSXR_Rider

For the past few years I've wanted a 370z Nismo, my timeline for a purchase is 4-6 months from now but could be much sooner if I come across a deal too good to pass up on. I've test drove the base model a few times so I have some idea of what the car drives like and know what I am getting into.

I was originally only looking for a 2012-2014 370z Nismo, however decided recently to expand that range to include the 2011 year model as well. My understanding is that there is very little that has changed over the years.

From research I have done I know that the early model 370z Nismo's suffered from steering lock and transmission issues, though I think this was limited to 2009-2010 year models.

What I'm really trying to determine is the following:

1. Were 2011 370z Nismo's affected by steering lock or transmission failures seen on the 2009-2010 models?

2. Aside from that what else can I expect to run into with a used example of a 370z Nismo from 2011-2014?
