Here's what happens to the car:
* It's given to Percy Jackson by Hermes as a way to travel safely on his quest. The car is a magical vehicle with enhanced speed, defense, and even the ability to fly for short distances.
* It is often a source of humor and mischief: The car has a mind of its own, sometimes driving recklessly or even trying to eat people!
* It provides protection and transportation: The car helps Percy and his friends escape dangerous situations, and it's a crucial tool for them to navigate the quest.
* It's a symbol of Hermes' presence: The car acts as a reminder that Percy is never truly alone, as Hermes is always watching over him.
While the car isn't destroyed, it's not mentioned what happens to it after the quest is finished. It's possible that Hermes kept it, or that it was returned to its original state. However, its role in the story is significant, and it's a key part of the journey for Percy Jackson.
