AVIS, as one of the leading global rental companies, engaged in deceptive practices during the car return process. They altered the return time and charged nearly 90 euros for a full tank of fuel despite the car being returned with a full tank. Thankfully, I kept the fuel receipt and dashboard photo from before the return, which allowed me to get the money refunded.

We booked a BMW, but they gave us a Renault and refused to refund the difference.

We rented a car in Seville and a hotel staff member crashed into our car. The rental company immediately charged our credit card. We had purchased the super insurance from the rental company, but it's been three months, and they refuse to compensate us for various reasons. We regret not buying the rental company's full insurance. We've never had an accident before, and it feels like the rental company's insurance is a joke. I strongly recommend everyone to buy the rental company's insurance directly—do not purchase insurance from the rental company. Learn from my experience. It looks like I'll have to go through the insurance regulatory agency for this.

Hardly any queues

I always use Avis when renting a car abroad. It's pretty good, but sometimes their process is quite slow.
