It's okay. Because we only had one credit card, they swapped us to a Peugeot 5008 for the same price.

They upgraded our rental from a Volkswagen Touran to a Mercedes without informing us. Driving a 9-seater Mercedes in Spain was a nightmare, and the car was in poor condition. It even broke down halfway.

Speechless, forced to purchase insurance for 450 euros

Booked with full insurance that included a one-way drop-off fee, but at pick-up they said nothing was included and still held the money.

When we arrived at the airport to pick up the car, they required us to present two international credit cards for the driver as a guarantee. Avis explained that it was because we rented a high-end car, an Audi A4. I felt it was unnecessary. After some negotiation, they gave us a smaller Infiniti mini wagon. Although Avis said it was a downgrade, the car we got was brand new. Amazing!
