TCC Rating
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 2007 Acura RL is a top-notch luxury sedan that’s sportier than its conservative exterior might indicate, yet those who want to be seen―or have a V-8 under the hood―should look elsewhere. The 2009 Cadillac STS isn’t a standout for looks, but you’ll appreciate the way it drives.
