TCC’s Bottom Line
No matter whether it's a coupe, convertible, or Gran Coupe, the 2014 BMW 6-Series covers soft and elegant as well as it does sharp and athletic. The 2014 Mercedes-Benz SL Class feels content as a grand tourer, but it's sportier than you might expect. The 2014 Porsche 911 range spans a broad spectrum, but somehow manages to hit exactly the right marks at each point, balancing performance, features, and practicality almost perfectly.
