I have rented cars a few times before, and Barcelona Airport in Spain is the worst. I saw many reviews online saying that they rip off Chinese customers, either by forcing you to buy extra insurance at pick-up or by charging ridiculous fees for minor damages when returning the car. At the AVIS Barcelona Airport branch, I returned the car during business hours and requested an on-the-spot inspection, but the staff kept saying they were about to leave and asked me to leave the keys in a box. The next morning, I received a text message on the flight saying that my credit card was charged 678.91 euros due to damages. I'm sure I drove carefully and there were no damages. I have photos from the time of pick-up, and now we are going back and forth. Even though I bought full insurance, which should have been handled by the insurance company, I feel it is unfair to be falsely accused like this.

Average. The rental company didn't inform me in advance through any channel that I needed to bring two credit cards. They insisted, 'no card, no car,' which made me very angry. No matter how I explained or offered to pay a cash deposit, it didn't help. I had no choice but to return to the hotel to get another credit card. But what if I hadn't brought another one when I left the country? Would I have paid but not gotten the car? Unbelievable.

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

The procedures were very smooth. They changed the pickup location to one closer to my hotel directly at the pickup site. However, the in-store staff suggested buying full insurance, which was quite expensive. The cost of full insurance for 9 days was the same as 9 days of car rental. Everything else was great. The car was relatively new.

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