Rented the car at CDG Airport T2 and returned it at T1. I booked a station wagon but received a Citroën C4 instead. It accommodated four people, three 22-inch suitcases, one 20-inch suitcase, and some soft bags, with no room to spare. The trunk seemed smaller compared to the Opel station wagon I rented before, which could fit four 20-inch suitcases and one 22-inch suitcase. The Citroën C4 had a 1.6T turbo engine, was fuel-efficient and performed well. The car came with GPS and was almost new with less than 4,000 kilometers on it. At return, the customer service agent thoroughly inspected the car with a flashlight, which was the first time I encountered such diligence in my years of self-driving. The contract stated to return the car with a full tank, but I got it with three-quarters of a tank. When returning, I filled the tank and drove another 40 kilometers, essentially returning it full. It is important to take pictures and clearly communicate with the staff during pick-up and drop-off to avoid any misunderstandings about the fuel level.
