They force you to buy additional insurance, otherwise they won't allow you to cross the border. The crossing fee is only 25 EUR, but the insurance costs 66 EUR plus tax, which altogether cost an extra 120 EUR. I booked a C-class but got an X1 instead, which is clearly not the same class in China. Maybe in Germany, X1 has the same price as C-class. I've had a good impression of Hertz before, but this experience was very disappointing. The staff refused to mediate over the phone with the booking agency. It was really frustrating. If I weren't in a hurry, I would've canceled the rental. Do not choose this company.

The process was quite simple. They only asked if I was sure about purchasing insurance. Seeing that we had a lot of luggage, they suggested upgrading to an SUV for an extra 25 euros per day. We got a Volvo XC90 with a navigation system, which was incredibly helpful. Otherwise, it would’ve been difficult to access Google Maps with local data, and Baidu Maps isn’t very useful here. Make sure to bring your domestic driver’s license and its translation; otherwise, they won't include it in the record. I forgot mine and almost had a serious issue, but fortunately, someone else had theirs.

The vehicle was in great condition and fuel-efficient as it was a diesel. The staff were friendly, but there was no one to accompany me for an on-site vehicle inspection.

The service was excellent. It was very easy to find the car at Frankfurt Airport. Upon return, just follow the signs to locate it. The car inspection during drop-off was very quick. They gave me a free upgrade from a BMW 3 to a Volvo XC60.

The store is quite easy to find.
