Saturn's cars are now better than they ever have been. When it appeared in 2003, the Ion represented a major improvement over the old Saturn S-series. The most substantial changes came for 2005: Larger and more supportive seats have replaced the barstools used previously, and a larger steering wheel provides a more comfortable grip. Suspension tweaks have resulted in a smoother and quieter car that's more pleasant in everyday use. At the same time, the handling is sharper, making it more fun to drive. The improvements continued for 2006: Saturn has reconfigured the center dash to provide more room for storage and to enhance legroom. OnStar is now standard on all Ions. , ,
