In our home country, we took the same car with the same people and luggage to the airport, but the staff here insisted that the Mercedes C-class couldn't fit our luggage and asked us to pay for an upgrade to an Audi A4 wagon. Coincidentally, another customer nearby was also asked to upgrade. It seems the reviews about forced upgrades are true. We were in a hurry, so we had to upgrade. Fortunately, the A4 was a diesel car, as I hoped, and had only 3277 kilometers, almost brand new. When returning the car, the staff inspected it very carefully, noticing a tiny chip on the windshield caused by a small stone. Thankfully, we had full insurance. I checked the windshields of a few nearby cars and saw many such tiny chips; the company considers them as damage. I suggest getting full insurance when renting a car. Overall, the car was fine, but after driving 1000 kilometers, it indicated that it needed one liter of oil, quite similar to domestic Audi cars needing oil for long trips.

The service staff were polite and did not forcefully sell insurance. The efficiency of car return inspection was also high. It's just that it was hard to find the service personnel when picking up the car, but there were no major issues. When leaving with the car, the first gate was to take a ticket, which was a bit confusing at first on how to proceed, but fortunately other people in their cars gave tips.

The staff were quite patient.

Satisfactory

This time we rented a car from Europcar, a well-established European car rental company. We picked up the car at Frankfurt Airport in Germany. The car was very new, and we didn’t encounter any forced insurance sales. Despite our not-so-great English, the counter staff was very patient with us and provided good service. We returned the car at a drop-off point in downtown Vienna. Since it was a Saturday and the rental company was closed, we followed the instructions for self-service return, parked the car in the designated spot, and dropped the keys in the box. The pick-up and return process went very smoothly.
