2005 Chevrolet TrailBlazer EXT LS 4WD 4dr SUV (4.2L 6cyl 4A)


We purchased a used 2005 Trailblazer EXT to replace a Chevy Astro. Although the TrailBlazer has almost 70 more horsepower it has worse performance than the old Astro. It also gets worse gas mileage. Duh - we could have had a V8.

Best Features

Quiet ride. Smooth transmission. Roomy interior. Nice towing package.

Worst Features

More power, less weight. Not relevant since Chevy dropped the EXT version. Need to improve drivetrain design of extended models. What works for the standard size doesn't work for the extended.
