The Car Connection's Take
TCC Rating
8.2
9.0
TCC’s Bottom Line
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.
