The provided car model was not very satisfactory. It's unclear if it was an upgrade, but the power and fuel efficiency were not as good as the vehicle booked.

Very good

We arrived at the scheduled pickup location before the reserved time, only to be told that our reserved car had been returned to another location by the previous customer. We were told to pick it up ourselves from the other location. The staff showed no sense of responsibility, with an attitude like, 'Just go get it yourself.' We had no choice but to take a taxi to the other location, and we are still negotiating compensation with the car rental platform. Despite agreeing to return the car to our scheduled drop-off point, we were charged a one way fee again when returning it, with the staff's attitude being consistently poor. It was a bizarre car rental experience with chaotic management and no sense of service. By the way, the store is actually Hertz.

There weren't many people at the store, so we were helped immediately. The only issue was that they gave us the keys and told us the parking spot number, so we had to find the car ourselves, which took us a while.

I have rented cars in Germany twice. The first time I rented an Audi A4 estate, but since they didn't have it, they upgraded me to a Volvo XC60, which was okay. This time I booked a Mercedes E-class estate, and again, they didn't have it, so they upgraded me to a Volvo XC60. Initially, I was a bit upset, but I found the XC60's noise insulation to be much better than the E-class estate I rented in the UK, and it had more space. The interior quality is much lower, and the driving feel of the Mercedes is definitely a class above Volvo.
