The Car Connection's Take
TCC Rating

8.4
TCC’s Bottom Line
With the addition of a new four-door Gran Coupe and M6 Coupe, the 6-Series lineup covers the full range of personal luxury, from soft and elegant to sharp and athletic. The 2013 Mercedes-Benz SL Class toughens up its image and its handling, but still feels more content as a grand touring grand dame.
