We have a 2011 and 2013 in the family. Yeah the 13 is new by the other is just hitting 4000 miles so I'll call that year old new. I won't say the difference is one = marshmallow but we had a stretch of bad cross winds on freeway yesterday and the 2013 was definitely better.
With the 2013 better in cross winds and both just fine otherwise I'm thinking one should choose the 13 if they can.
