Buick has long been trying to shake off its image as a boring brand that sells boring cars to boring people. To further distance itself from that notion, GM designers created the Avista concept car, unveiled at this year's Detroit Auto Show. It's a 400 horsepower rear-wheel-drive performance model. This is one concept, though, that GM is unlikely to actually produce. Buick is aiming for more excitement, but perhaps not this much.
