AVIS is a very professional car rental company. The counter is right at the exit of Chiang Mai airport. Even though I don't understand English, I quickly completed the procedures. The staff at Phuket airport were also very professional when I returned the car. It was an enjoyable car rental experience.

The staff at the rental point did not speak Chinese when I picked up the car. After a brief English introduction, they asked me to sign. However, when I returned the car, a staff member who spoke Chinese was quite helpful.

Compared to last year, Avis did not overly recommend insurance this time, but they were very strict with verifying the translated documents and did not provide any additional assistance such as printing services. The staff seemed quite indifferent, as if they didn't care whether you rented a car or not. We had to make three trips before successfully renting a car, though part of that was due to our own issues. Additionally, renting a car on-site without a reservation can be cheaper, but there is no guarantee that cars will be available. We also asked other rental companies nearby; there was a Thai local rental company next to Avis that was much cheaper, but they required notarized documents.

Pretty good.

Note, there is an AVIS store at the airport arrival exit, but no one was there. I called their customer service, and they said someone would be there soon, but after waiting for more than ten minutes, no one showed up. Later, I asked the neighboring car rental store, and they told me that AVIS has another larger store at the other end of the airport hall.
