Easy and fast

When picking up the car, I was informed that it hadn't been returned yet, so we had to wait around 2 hours.

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.

Pretty good.

Hertz did not supply the ordered car but different model ,the guy at the counter was very rude .
