The announcement of the 2003 Saab 9-3 Sport Sedan is backed by the biggest investment program in new models and production facilities in Saab's history. The new car, launched in four-door sedan form this week, will be followed by cabriolet, five-door hatchback, station wagon and crossover versions and is the first step in a five-year growth plan intended to boost annual sales to over 200,000 cars from the current 130,000.
