How does the
TCC Rating work?
The TCC Rating is a clear numeric rating value based on a 10-point scale that reflects the overall opinion of our automotive experts on any vehicle and rolls up ratings we give each vehicle across sub-categories you care about like performance, safety, styling and more.

Our rating also has simple color-coded “Stop” (red), “Caution” (orange),
or “Go” (green) messages along with the numerical score so you can easily understand where we stand at a glance.

Our automotive experts then also collect and show you what other websites say about these different aspects of any vehicle. We do this leg work for you to simplify your research process.

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.
