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 You should only consider the 2008 Chevrolet TrailBlazer if you frequently tow; even then, most truck-based alternatives handle much better. Unless you love the style or genuinely value the off-road capabilities of the 2008 HUMMER H3, it doesn’t realistically make a very good everyday SUV.
