I have a 2013 auto base in black. From what I could see, there is no real difference between the cars at all except for 13 having a battery access panel cutout in the trunk. They say the interiors have been upgraded, but I failed to see the difference between a 2011 and my 2013 side by side at the dealer.
Remember you can plastidip or wrap the car for $500-$2500 and do whatever you want to the color at any time (look up my thread on plastidipping my starlight Evora to matte clear black - I even did the wheels copper). Shouldn't really be the deciding factor anymore in 2014 unless you're really smitten with deep luxurious glossy paint, which I can also totally understand.
