Just purchased a 2012 200 sedan with 61xxx mikes nice car. But hiw do you tell which model you have I think its the touring but not quite sure. And possibly the 4 speaker model which I want to maybe add more than the 4 to it. It has the radio with Siriusxm and a sun roof which is why I belive it to be the touring. Any info is greatly appreciated. I'm coming from a 2011 Chevy impala that i hated so I like this change very much.
