Saabs are supposed to revel in their quirkiness, though that historic image has dwindled somewhat since General Motors purchased a controlling stake in the Swedish automaker in 1990. Perhaps no single model has served to diminish the brand's identity more than the 9-7X "Trollblazer" SUV (though the 9-2X "Saabaru" would certainly serve as a close second). Based on GM's GMT360 platform that's shared with the Chevy Trailblazer and GMC Envoy, the 9-7X is pretty egregious in all of its guises, but we're specifically waving our fingers at the Aero model, which is powered by the same LS2 engine that could be found nestled under the fiberglass bodywork of the 2005-2007 Chevy Corvette. Yes, it's fast, and yes, this is the best Trailblazer ever. Regardless, what's a Corvette engine doing in a Saab? Darned if we know. 26/12/08
