To know the *exact* options available on a *specific* Pontiac G5, you'd need to consult:
* The original window sticker (Monroney sticker): This sticker on the car's window (if the car still has it) shows every option installed on that particular vehicle.
* The vehicle's owner's manual: This will list the features included with your specific model and trim level.
* Online resources: Websites like Kelley Blue Book (KBB) or Edmunds may have option details based on the year and trim level. You'd need to input the year and specific trim level (like G5 GT or G5 Base) for the most accurate information.
Remember that options were often bundled into packages, meaning that certain features were only available together.
