The 2007 Chevrolet TrailBlazer is part of this SUV's second generation. It comes in three trims: LS, LT, and the performance-focused SS. Each model features a 4-speed automatic transmission and either RWD or optional 4WD. Base models have a 291-hp, 4.2-liter inline-six, while the SS gets a hefty 395-hp, 6.0-liter V8. While not as modern as its successors, the '07 TrailBlazer had decent tech for its time, including OnStar telematics and optional navigation, rear DVD entertainment, and a Bose premium audio system. Safety features comprised of dual front airbags, ABS, stability control, and tire-pressure monitoring.
