Before I considering the rent a car, I read a lot of good and bad reviews. However, I need to rent a car. I was so worry due to some bad experience from others, complicated procedures etc. I’d say, my experience with Trip.com / Avis is pretty good and smooth. I think Avis upgraded the car for me without additional charge. I got a bigger car, the car is new and clean. Easy to get and return the car. Thank you
