SL vs. SL

Compare and contrast.  It’s not hard to spot the exterior differentiation on Mercedes’ latest SL hardtop-roadster.  Other differences can be found under the hood, inside the cockpit, and underneath the bodywork.  We all know that, despite the SL’s greatness (#1 High-End Grand Tourer here at GCBC), Mercedes-Benz SL buyers are entranced by the 3-pointed star and the look of the vehicle.  So, how do they compare?
