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.

Unjustified charges: 1. When returning the car, no inspection was performed. Instead, they asked if we were going back to Rome or taking a flight, then simply said 'ok.' It's not acceptable to claim they were busy and let customers leave first, as we saw three employees leisurely smoking. 2. There is concrete evidence that the staff lied. We had just filled up the tank a few kilometers from the airport, but they charged us 15 EUR for an 'empty tank' after we left. 3. They fabricated car damage. No accidents occurred during our rental, and the damage was not confirmed with us on the spot, yet they charged us 291.69 and 67.2 EUR. 4. If this is an issue of individual employee integrity, then failing to thoroughly investigate and reasonably explain to customers is a problem with Avis as a company.

The car we booked wasn't available, so they upgraded us to a Volvo V60. Although the rental cost increased a bit, it was still worth it.

Avis is considered a high-end rental company, there’s nothing to criticize.

Attitude is average, service is average, phone calls are not answered, and the company prioritizes its own interests.
