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.

I was promised a Mercedes Thunder or a similar class vehicle, but was given a Fiat. How is a Fiat considered the same class as a Mercedes??? Moreover, this Fiat only has one door on the right side in the rear; there's no door on the left side, so you can only enter from the right. The first seat you encounter is broken (the seatbelt doesn't work). Seriously, I'm baffled. How can they rent out a car like this?

Very dissatisfied. The original vehicle was unavailable, and I had to either downgrade, pay more for an upgrade, or cancel the order.

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 staff at the Rome airport counter spoke very poor English, hardly understandable. They kept pushing for full insurance, and seemed very displeased when we declined. They gave us a subpar car despite our large luggage. At the parking lot counter, they kept stalling and refusing to change the car, only offering a FIAT500 convertible, which was a struggle to fit our luggage into. I was quite dissatisfied with the service attitude of the Rome airport staff, but to avoid affecting our itinerary, I didn't argue further.
