Here's a great video of the Trailblazer at the Auto Shanghai show in China. It gives a closeup look at the Trailblazer's exterior. Since it's a Chinese version it could be a bit different than the American version.
TFLnow posted this video from the LA Auto Show of them talking about how the Trailblazer is a better deal than its sibling the Chevy Trax. They make a compelling case and I'd definitely pick it over the Trax.
