Pontiac, who invented the muscle car and defined a generation, is going out of business on Sunday. "The 84-year-old brand, moribund since General Motors decided to kill it last year as it collapsed into bankruptcy, had been in decline for years. It was undone by a combination of poor corporate strategy and changing driver tastes. On Oct. 31, GM's agreements with Pontiac dealers expire," MSNBC said. "At Pontiac's pinnacle, models like the GTO, Trans Am and Catalina 2+2 were packed with horsepower and sported colors like "Tiger Gold." Burt Reynolds and Sally Field fled the law in a Firebird Trans Am which raced through the 1970s hit movie "Smokey and the Bandit."," CBS said. Prior to GM's bankruptcy, Pontiac's sales had fallen from their peak in 1968 of nearly one million cars.
