Pros: They were quick to help us get the car checked back in so we could make our flight.
Cons: The agent asked me for the "passport" for the car. I had no idea what this was or where it was located. I thought he was referring to the paperwork I'd signed in Paris which we'd misplaced. Only after he pulled the documentation from the glove box did I understand what this important paperwork was and where it was located. The agent in Paris never mentioned this paperwork to us when checking out the car.
