The main reason is it's very convenient. You can pick up and return the car directly at the airport.

Picking up and returning the car at the airport is very convenient. Having a car available upon arrival greatly improved the efficiency of the entire trip.

A bit of a rip-off. The attendant told me that gas was expensive outside and suggested I return the car with an empty tank, and they would refill it for cheap. However, they charged me for a full tank at their 'cheap' price, so I ended up losing a lot. Make sure to return it with a full tank! Also, their recommendation was not good at all. Who would return a car with an empty tank without worrying about running out of gas on the way to the airport? It wasn't actually cheaper at all, don't listen to them. Additionally, they charged me $15 for airport parking, which was really frustrating.

The first car we got was a Toyota that smelled like rotten fish, so we switched to a Dodge. When returning the car, the staff said there was a small chip on the windshield and blamed us for it. Honestly, the chip was very tiny, and we only drove in the city for three days, so it shouldn't have happened. We suspect it was there when we picked up the car, but the garage was quite dark, and we missed it. Interestingly, another Chinese customer before us was also blamed for the same reason! So, friends, be very careful when picking up your car! Don't trust the rental company blindly!

Pickup was very convenient, and the vehicle was quite new. However, the hard sell on additional insurance was unpleasant.
