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 If you can get past the often-confusing iDrive system, the 2012 BMW 1-Series offers a great blend of style, power, handling, and luxury at a sometimes reasonable, sometimes objectionable price. The 2012 Porsche Cayman is a potent mix of performance, comfort, and cargo space, and a leader in the sports car segment.
