The Car Connection's Take
TCC Rating
8.4
8.2
TCC’s Bottom Line
The 2016 BMW M6 is a no-compromises kind of car for buyers unfazed by traditional sports car manufacturers. It's better suited for the streets than the track, and that's not a bad thing. The 2016 Mercedes-Benz SL-Class offers relaxed luxury and willing power, but delivers nimble moves when called upon.
