The Car Connection's Take
TCC Rating

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. From the satisfying Carrera to the outrageous GT3 RS, the 2016 Porsche 911 is consistently brilliant, and lives up to the this model line's pedigree in every respect—with some modern comforts spliced right in.
