This is not true. Mid 2011 Nissan stopped using the dreaded steering lock.

OP, if you're going to go with a 2011 make sure it doesn't doesn't have the steering lock.

09 in cabin filter wasn't standard and nav resolution was weak.

2010, heated mirrors were added and brighter nav, 40th introduced as well as convert. trunk cover brackets were standard.

Suspension spring rates actually changed in 2011. The dealer maintenance spec sheet showed the difference and every mechanic in my dealer asked me how did the 2011 feel to me. The suspension felt slightly softer and went over bumps better compared to my 09. My 09's stiffness inspired more confidence.

In 2013, they followed up with the sifter springs with "euro shocks", making the Z even softer.

2012 brought the oil cooler.

2013 brought the refrshed grille and wheels.
