Returning the car was smooth, but it was slow because there was only one staff member.

When I picked up the car from Europcar, there was no one to inspect the car with me, and the counter didn’t mention this. As a result, when I returned after driving for an hour to replace the car, they found new damage, but I had no evidence. This is a lesson learned; I will ensure to inspect the car first in the future.

It's okay.

Couldn't find the pickup location, and later confirmed the car was not delivered to the scheduled pickup point.

1. The pickup location couldn't find the reservation, and we were directed to another branch; 2. The car class was downgraded, we got a SKODA FABIA in poor condition, unsuitable for driving in the Black Forest area; 3. The designated return spot at the central station was insufficient, requiring a long queue at the only counter to fill out forms, almost missed the train; 4. The actual rental company was EUROPCAR. At pickup, another family was also complaining about poor service... Haha!
