Chevrolet Trailblazer EXT Model Overview

The Chevy TrailBlazer EXT is a vehicle so big...so exciting...so new....that it warrants its own model rather than becoming just another trim for something else. Created in 2004 and gone by 2007, the TrailBlazer EXT is a TrailBlazer with enough add-ons to earn it three extra letters at the end, all capitalized.
