Similar in almost every way to the 2005 edition of the Trailblazer SUV, the 2006 TrailBlazer EXT returns with its 4.2-liter inline 6-cylinder engine, rated at 291 horsepower (at 6,000 rpm!) with 277 lb-ft of torque. The TrailBlazer EXT comfortably seats 7 (although some owners we spoke with disputed this claim) and is priced reasonably enough, between about $24,000-$31,000 dependent upon engine type, options and of course rear-wheel drive vs. 4-wheel drive. Mileage is as you would expect it, a relatively low 15 mpg city/20 highway. Fans of the vehicle claim the cost of gas to be worth the quality of the ride.
