Relatively reliable.

I rented a Volvo XC60, but they gave me a basic Mazda hatchback instead!
Since I had already checked online beforehand, the Avis front desk did not explain anything and directly handed me the keys. It was only when I got to the parking lot that I saw the car. XC60 and Mazda hatchback are considered the same class of vehicle???
XC60's equivalent class should be Audi Q5 or BMW X5/X3, right?

There was no staff to check the car at the pickup parking lot, but the deposit was returned quickly when returning the car, which is great.

The service was pretty good.

There were many people waiting to pick up their cars at Avis, so it was a bit slow. Since we had a lot of people and luggage, we booked a 7-seater car but were given a Sharan. However, I suggest that a Sharan is really not suitable for driving on those roads; the driving experience was much worse... Also, the Avis staff member was always lethargic. He told us where the car was parked, but after looking around three times, we couldn't find it. When we asked him to help us find it, it turned out they had parked it in the wrong place... This experience was a bit disappointing...
