The car exchange process was very convenient.

Had to wait two and a half hours to pick up the car at Charles de Gaulle Airport T1. Arrived at 8:30 AM for a 9:00 AM pickup, but was told to queue again, which delayed us until 10:30 AM without any cars available. Finished paperwork but had to wait even longer for the keys. It was incredibly frustrating.

The service was very attentive. A very professional car rental company.

French efficiency is indeed low, the most unreliable thing was that the car indicated low oil level in less than a day. We were two girls, confused and called their customer service, using up all our phone credit, and still no resolution. They even asked us to call the Belgian hotline, which was ridiculous. Ultimately, we found a solution through Baidu and a friend's guidance to check the oil dipstick. Fortunately, there was a garage nearby, where we found out there was almost no oil left, any further driving could have damaged the engine. We spent our own money to add oil and coolant, and after that, everything went smoothly. The car had only driven a little over 10,000 kilometers, quite new for a rental car, and yet this problem occurred. When we returned the car, we informed the staff and they said they would deduct the repair costs from the fee. The final bill showed a reduction, but it was charged in dollars with Dynamic Currency Conversion, causing some exchange rate loss. I generally like HERTZ, and despite experiencing the unreliability of the French service, everything went relatively smoothly otherwise.

The lady at the front desk in France was really nice and efficient. The first car we got was an Opel, but the trunk was too small. After mentioning it to the front desk, they swapped it for a Nissan, which was still small, but we didn't want to complain further, so we made do. So, don't pick up your car at 8 AM! It's very important. They tend to give you less desirable models first. My luggage, which was 26 and 22 inches, couldn't fit in the trunk, one had to be placed in the front seat.
