Last week we brought you spy photos of the 2011 Mercedes-Benz SLS AMG Convertible, and today we’ve got another slightly more revealing look at the model. The retractable roof is still heavily masked, leaving us to speculate about both its exact contours and construction, but up front we now have a much clearer view of the front apron. The rear is also still heavily masked; however, with a little imagination you can probably surmise fairly well what the back is going to look like.
