Disappointed to find that we were going to be charged for minor rim scratches. Please follow up

Free upgrade to Volvo XC60

The car provided by the Vienna main train station branch had a chip in the windshield. It is irresponsible to assign such a vehicle with safety hazards to a customer renting for 11 days. As expected, the windshield began to crack after one day of driving, and it got progressively worse, forcing us to replace the car in Innsbruck. The replacement car had seat safety issues, causing a one-day delay in our entire trip.

The car pickup process was very smooth, and the staff were very nice. They drove the car directly to the pickup point for handover, so I didn't need to find it in the parking lot myself.

Too many pitfalls! Frequent charges for minor scratches without any notification! I had to disable my credit card's international payment feature!

I booked a Mercedes, but was given a Hyundai i30 at pickup, and they insisted they are in the same group, like BMW... How can Mercedes and Hyundai be considered the same tier? Why doesn't the website specify Hyundai when booking, but give a Mercedes at pickup? After a lot of back-and-forth discussion, they finally gave me a Citroen. However, the car's condition was decent and fairly new.
