I suspect that within 10 years, GM will be Chevrolet, Cadillac and GM Truck. No more Buick or Pontiac, both trucklines combined, and they'll see their market share decline even farther. As long as GM stuck to the Sloan Hierarchy, they did well. When they got into the cookie cutter business, and tried to sell zooted up Chevy Cavaliers as Cadillacs, that's when they pulled the rug right out from under themselves. I have no sympathy left for them. Ten years of Saturn, and still hasn't turned a profit, and they buy a floundering Korean company, and let their bread and butter fall butter side to the floor.
