The 2005 Chevrolet TrailBlazer EXT, part of the car's first and only generation, is a mid-size SUV with the comfort and space of a larger vehicle. It comes in LS and LT trims. Available with a two-wheel or four-wheel drivetrain, it is powered by a robust base 4.2L inline-six engine that delivers 275 hp or an optional 5.3L V8 engine with 300 hp. Both engines pair with a 4-speed automatic transmission. The model features a spacious, seven-seat cabin, plenty of cargo space, and towing capacity of up to 7,200 lbs. Hi-tech features aren't its strong point, but it offers an AM/FM radio with CD player and premium speakers, OnStar telematics, and dual-zone climate control. Notable safety features include front airbags, ABS, and stability control, although critics have noted that side curtain airbags were not an option.
