We needed a small car for a short trip, but when we arrived 30 minutes early at the car rental company, they told us there were no cars available. They offered an upgrade for an additional 20 euros per day or we could wait for more than half an hour. Since an automatic car is more convenient, we accepted the upgrade. Hertz has always provided good cars, and this time it was a car with just over 10,000 kilometers on it. It worked great over the past few days. Returning the car was also easy, no issues with insurance. We returned the car a day early due to a change in plans and asked if we could get some discount for that, they agreed initially but didn't give any discount in the end.
