I've always rented from HERTZ, and generally, there are no issues. I've encountered both enthusiastic and average staff, and I've never had to wait in line.

Very easy to find the rental location. Although there were many renters, the process went very smoothly.

Out of nowhere, they requested some number, and even after calling the car rental customer service, they couldn't figure out what number it was. It took more than half an hour without providing any number before the rental was completed. I still don't understand the whole situation!

Pretty good

This was the worst car rental experience I've ever had. Initially, we planned to pick up and return the car at the airport, but we returned it a day early at the Frankfurt train station. We specifically asked at the counter if there would be any extra charges and if the rental fee would change. I was okay with paying a fee for returning the car at a different location. The frustrating thing was the staff at the Frankfurt train station assured us that if we returned the car a day early, they would refund one day’s rental fee to our credit card. We happily returned the car, but after we got back home, we received a bill showing an additional charge of about eleven hundred yuan for five days of rental. We tried repeatedly to communicate and appeal with Zuzuche to no avail; they required evidence of our conversation with the employee at the Frankfurt Central train station. It's ridiculous, how are we supposed to provide that after returning home??? This was an extremely frustrating car rental experience.
