Booked a Mercedes, ended up with a Ford. There were at least two similar Mercedes parked nearby. When I asked customer service, they said it's the same grade and refused to change.

Did not specify the required gasoline type, leading to unnecessary detours.

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

Fast and friendly counter service, excellent car condition.

The trip was full of unexpected events! To summarize, we had a minor accident during the journey. We called Hertz's international emergency assistance, and the German customer service patiently handled all my silly questions and helped us find a nearby replacement vehicle. Thanks to them, our trip was saved. 5 stars!
