Saturn Ion is an inexpensive compact that emphasizes style and innovation as well as value. Ion was all-new in 2003, and significantly larger than the Saturn S-series model it replaced. The 2004 Saturn Ion features some significant updates, including higher-grade interior fabrics and richer-looking interior trim in more harmonious colors. Additional sound-deadening material brings a quieter cabin. The stereo systems have been improved and is available with an MP3 player, XM Satellite Radio, and a six-CD changer. Ion's steering has been re-calibrated for improved road feel at speed. Both of the available automatic transmissions have been refined as well. And Saturn has injected some real excitement into the Ion for 2004, with the uniquely trimmed Special Edition sedan, and the supercharged Red Line coupe. Dent-deflecting and rust-resistant plastic body panels add to the Ion's appeal. Acceleration is good for its price class, ride and handling about average. In interior comfort and refinement, Saturn still has a way to go. But experience has shown that people choose Saturns as much for the hassle-free buying experience as the for car's actual character and performance. In fact, Saturn ranks at or near the top in J. D. Power and Associates Sales Satisfaction Index surveys, putting it in the same league as Lexus and INFINITI in terms of satisfaction with the sales experience.
