The 2008 Isuzu Ascender should be considered a bargain midsize SUV. Based on the Chevrolet TrailBlazer and other GM midsize SUV offerings, the Ascender offers a cavernous 80.1 cubit feet of cargo space. Its 5,800 pound towing capacity ranks near the top of the class, as does its seven-year/75,000-mile powertrain warranty.
