1. The actual cost was almost twice the amount shown on the app. 2. Although the app already included basic insurance, the staff insisted on purchasing full insurance, which resulted in double coverage. Even after returning the car, I still haven't seen the insurance policy. What happens if something goes wrong? All the risk is on the customer. 3. I never saw the official rental contract, only a vehicle inspection checklist. 4. The app included the option to return the car at a different location, but the store still charged extra fees. 5. No itemized receipt was provided.

It's fine.

The staff’s English was easy to understand and he was very polite. Even though the fuel was a bit low on return, he didn't mind. After refueling, we drove for a while. Time was tight and the Frankfurt airport area is quite confusing, so we didn’t look for another gas station nearby.

I am very satisfied with the service. It was easy to find the car rental counter at Frankfurt. The car was in excellent condition, having only 5000 kilometers on it.

The counter service was enthusiastic and the procedures were quickly completed, but we were not satisfied with the car pickup. We booked a German car, but we were told only Japanese cars were available unless we paid extra to upgrade to a German car. Really frustrating. We rented three cars, and one of the Audis had an alarm issue on the second day. It was difficult to contact the rental company by phone, but luckily we found an Audi service center that helped us resolve the issue. The rental company gave no prior warning and their phone line was always busy. We will definitely not choose this rental company again. Additionally, the rental location was easy to find, but the return location was extremely difficult to locate.
