While the basic design for the 900 model of the early '90s was 20 years old, these cars aged well. Taking a look at the model lineup, both the base 900 and 900S came in 2-door hatchback and 4-door notchback formats, powered by a standard 2.0-liter 4-cylinder. The 128-horsepower engine came paired with either a 5-speed manual or 3-speed automatic transmission. Next in line were the three Turbo models in 2-door hatchback, 4-door notchback, and 2-door convertible configurations, plus the top-end Turbo SPG 3-door. All featured a turbocharged version of Saab's 2.0-liter 4-cylinder, also available with either a 5-speed manual or a 3-speed automatic gearbox. Features added in 1990 included antilock brakes, a driver-side airbag, and a new 18-gallon fuel tank.
