We initially booked the rental car on Zuzuche for 1,375 euros, but when we got to Rome to pick up the car, they said we needed to pay extra because there were two drivers, raising the price to over 1,600 euros. We accepted that. During the trip, our car window was smashed by thieves, and when we returned the car to the Madrid Avis location, they charged us 480 euros for the repair, which we also accepted. However, Avis ended up charging us a total of 2,357 euros, at least 200 euros more than expected, and there was no way to dispute it.

Unreasonable extra charges! The car rental company offered the choice to return the car with a full tank or not, but despite refueling to a full tank, we were still charged over 100 euros! Throughout the trip, the fuel we purchased ourselves cost far less than these additional charges. During the return inspection, the engineer confirmed everything was fine but then turned around and deducted money from us, demanding fuel receipts. It’s absurd because self-service fuel stations don’t issue receipts! Honestly, AVIS uses their size to exploit customers. Extremely disappointing!

Quite good

Because I bought full insurance, they informed me that I didn't need to fill up the tank when returning the car; it's okay to return it empty.

The car model we booked was not available at all. When we showed the contract to the staff, they didn't care and said that the model in the contract was unavailable. We had to either accept the available model or not rent at all. Since it was midnight, could we really not rent? We ended up reluctantly accepting a smaller model. The trunk could only fit three suitcases, and we had to place another suitcase on the back seat, making the back seat extremely cramped. The journey was very uncomfortable!
