The queue was quite long, and the two-door Mini I reserved was not available; instead, I was given a Volkswagen Golf. They claimed it was an upgrade, but as a solo traveler, driving a four-door car with a longer body made parking in narrow European streets particularly difficult. Also, I had already selected and paid for full insurance online, but when I arrived at the store, they pushed an additional 90-euro insurance to ensure I felt safe driving away with the car. Furthermore, it is customary to receive a full tank of fuel when picking up the car and return it with a full tank. However, they charged a 90-euro fuel fee, stating that the fuel cost would be refunded based on the amount consumed upon return. After refilling the tank and returning the car, I expected the 90 euros to be refunded but only received 78 dollars back. The difference of over 20 dollars was labeled as a fuel management fee. When I complained, they gave this explanation, which seemed unreasonable. Based on this online reservation experience, I concluded that renting for 4 days was supposed to cost 660 yuan (4 days rental with full insurance) according to the online plan, but the actual cost was 660 yuan plus 90 euros for additional insurance and over 20 dollars for the fuel management fee, totaling over 1500 yuan. Next time, I'd prefer to go to the airport and compare the value-for-money options of different brands' stores before renting a car.
