Waited in line for almost two hours, only one staff member was handling service, the queue was about 50-80 meters long.

Very good

There are actually very few Viano models available from HERTZ. When we went to pick up the car, they didn't have any left. They said our luggage was too much and that vehicles of the same grade wouldn't suffice, suggesting we upgrade to a VITO116, and charged us an additional 400 yuan for the upgrade. In fact, we didn't see any other vehicles of the same grade as VIANO in the parking lot. The staff member (an old lady) didn't upgrade us for free but rather persuaded us to pay for the upgrade, which felt a bit dishonest.

The two staff members at Hertz Munich Airport were very nice. We encountered some issues when picking up the car, but after four to five hours of effort, they eventually managed to rent us a car. Returning the car in Frankfurt was very convenient; the staff just drove the car to check the mileage, and that was it. They didn't inspect the exterior, possibly because we had purchased the comprehensive insurance. We had reserved a BMW X3 but were given a Volvo wagon instead. The car was a diesel model, very new, with many features and a built-in German navigation system that was quite useful during our trip.

The service was good. Under a strong recommendation from the counter staff and considering the heavy snow, I bought full insurance. However, they upgraded the car model, so overall, it was quite affordable and reassuring.
