My ION has been great since the first day I drove off the lot 4 years ago. The gas mileage is great for my typical driving day, and the maintenance has been minimal- basic upkeep and tune-ups. This week was the first time I had any "problems". A few sensors had malfunctioned, causing the check engine light to turn on. I have had issues with it not letting me pull the key out from time to time, mentioned it to the service manager, and they have fixed it. Something was mis-aligned in the ignition housing. I am happy with my choice, and would be purchasing a new saturn if they still had the ION.
Gas Mileage, centered console (LOVE IT), sound system, BIG trunk, decent amount of space inside the car for passengers
