Pretty good overall.

Very good. The car was in great condition, and the service was professional. They confirmed I had already purchased full insurance and didn't push any additional unnecessary options. Although the vehicle's model was changed, it was neither an upgrade nor a downgrade, but coincidentally it was the same model I usually drive. Returning the car was on a Sunday (outside business hours). Since I chose to return the car in a small town (Wiesbaden, one-way rental), the store provided a self-service return option. It was an excellent experience.

Pick-up and drop-off were very easy.

The rental company made a mistake with the terminal. I booked a Passat, but they gave me a Peugeot 3008 instead. It seems the Peugeot 3008 is cheaper. Fortunately, the car comes with a navigation system, which is quite convenient.

No extra sales pitch, and the attitude was quite standard. However, I booked a VW Touran, but they didn't have it and gave me a KIA CARENS instead. She said the KIA is slightly larger than the Touran, which was true. The car was slightly bigger. But once on the road, I realized it was underpowered. We were three people, each with 2 large, 2 medium suitcases, and a backpack. On inclines, the car lacked power. On many mountain roads, we could only use 2nd or 3rd gear, with the slowest speed at 30km/h. Next time, if the rental company tries to give me a Korean car, I will refuse.
