It’s amazing how one little piece of bodywork can change the look of the car. On Porsche 911s, its all about what is out back. Ducktail, duckbill, whale tail, tea tray — I love them all. I also love that Porsche continues on with them despite probably not really needing them. Today, we have one of those with this 2013 911 Carrera 4S coupe up for sale in Michigan.
