For 2004, the 9-3 convertible has been given the same full makeover the sedan received last year. The convertible is available in Arc and Aero models and equipped only with the 210-horsepower engine. The highline Vector sedan has been renamed the Aero, and the midlevel Arc sedan now comes standard with a five-speed manual transmission, rather than a six-speed. Bi-xenon headlights are a stand-alone extra on all 9-3s, while rear parking assist is now available as a non-package option on the sedan. The Sport Wheel Package for the Linear and Arc now includes a tire-pressure monitor.
