The Oldsmobile Bravada is the most luxurious of three new midsize SUVs from General Motors. As the Oldsmobile marketers like to say, if there's an Aurora in your garage, a Bravada would make a perfect stablemate. Two dinosaurs. Each may be technically innovative, handsome, and a truly fine vehicle (the Bravada is more than that), but that doesn't guarantee survival. Two days after the press introduction of the Bravada, GM announced that it would be putting Oldsmobile down, after a 103-year run. To assuage any concerns about service, Oldsmobile is, for a limited time, offering a 5-year/60,000-mile warranty on its new vehicles. Redesigned from the ground up, the Bravada is an engineering knockout. By its progressive design, this vehicle has already made GM history. Dinosaur indeed. The Bravada makes the Jeep Grand Cherokee look like the dinosaur.
