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 2010 Cadillac DTS is a boardroom on wheels: Six leather chairs keep old men cozy in a wood-paneled room, and steering feels like it's done by committee. A soft ride and roomy interior still form the solid base for the 2009 Buick Lucerne’s appeal.
