If you had a choice between similarly equipped '11s or '12s, go with the newer model year. There were lots of little standard additions to the Charger, like a color EVIC, steering wheel paddles, bolstered sport seats, 8sp transmission, etc. Also the Dodge badge added the red hash marks, if that matters
I don't know why these weren't all included on the '11, but what can you do.
