The Car Connection's Take
TCC Rating
8.4
9.0
TCC’s Bottom Line
The 2013 Mercedes-Benz SL Class toughens up its image and its handling, but still feels more content as a grand touring grand dame. Still a tremendous value, the 2013 Porsche 911 range offers a great balance between dedicated sports car handling and daily practicality.
