Pickup and return in Frankfurt, via Cologne, Rothenburg, Metzingen, Schwangau, Berchtesgaden, Salzbu

The confirmed car model was not provided in the store. Even after contacting the rental company, we were still downgraded. The cross-border fee was less than 30 euros, but the tax was as high as about 12 euros; the tax accounted for nearly 50%.

Very good

I had already bought insurance on the app, but the staff on-site made me buy it again.

Hertz's service in Europe is also quite good. I used Hertz when I traveled to the US as well—picking up and returning the car was very convenient.

When we requested a driver change, they said it was not possible and instead suggested adding a driver. They didn't inform us that adding a driver would incur a fee, nor did they have us sign any documents. Halfway through, we received a bank deduction SMS. Calling the store yielded no response, and even when we got to the store in Fussen, the staff couldn't reach the Frankfurt store via internal phone or email. Rent-A-Car tried to help us contact them throughout but to no avail. Finally, when we returned the car, we argued our case and they didn't charge us the fee. However, this made us anxious throughout the trip, affecting our travel experience.
