Analysts are saying don't be surprised if GM's fourth-quarter earnings are not that good because it had to spend money on developing and introducing new vehicles. MINI will debut a concept in Geneva called the Rocketman, which is smaller than any car it builds now. Aston Martin just introduced its latest sportscar, called the Virage, which is powered by a hand-built 6.0-liter V-12 that cranks out 490 horsepower. All that and more, plus John answers your questions about ethanol, the Toyota Prius and much more in the "You Said It!" segment.
