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 2015 BMW Z4 is on the pricier side of the roadster segment, but it offers a nice blend of comfort, sport, and technology. The 2014 Mercedes-Benz SLK is the most conservative choice amongst its competitors, but the mini-SL makes for a charming, compelling choice.
