Seat bottoms are too short. Not enough leg room when the front seats are set back and not enough foot room. There is a metallic bar on the bottom of the front seats that take too much space in the foot wells for the back passengers. see full Saturn ION review |

The engine in my ION is SUPERIOR to the one that was in my 1997 SL 1. It is quieter ,quicker and overall a more efficient powerplant. I researched this engine online and i was impressed with the engineering that went into its design. see full Saturn ION review |

This car was underrated at the factory, and has been tested at around 220hp to the wheels. Also, it has a limited slip differential, and a tuned suspension. see full Saturn ION review |

The HP increase over the base engine. The supercharger is smooth in its operation and provides a good boost of power for passing. The vehicle still gets decent gas mileage with normal driving. It is a performance vehicle. see full Saturn ION review |
