Frankfurt-Würzburg-Munich-Heidelberg-Stuttgart-Rothenburg-Füssen

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.

Satisfactory

Due to a security incident at Frankfurt Airport, the entire airport was closed, causing the flight to be delayed. Upon picking up the car, I was informed that the booked and prepaid car had been rented out. Only one similar model was left, which required an additional payment of 5000 yuan for an upgrade. Communication with customer service was unsuccessful, and I had to pay extra to get the car.

We rented a car from HERTZ. The process was quite convenient and the staff were very friendly and nice. They checked our order, driver's license, age, and driving experience. The staff of the big company had a pretty good work attitude.

I originally booked a Benz C-class, but there were none available when I arrived. The store recommended a Ford Rega. Looking back, thankfully they gave us an SUV; otherwise, there wouldn’t have been enough space for the luggage of five people.
