After receiving the documents, they didn't assist immediately. The staff left the counter and returned only after about half an hour. They didn't provide a large car as per the rental agreement, instead gave a midsize SUV. After negotiating and finding another window, they finally agreed to change it. The entire pickup process took about four hours!

There were quite a few people in line, and with only a few counters, I waited for more than half an hour. However, the crowd indicates that AVIS is quite popular.

We went to pick up the car at noon, and the receptionist spoke Chinese. She told us that the car we booked was not available and that there were only two Korean cars left in the same class, which were of lower quality. She suggested that we upgrade to a new 2018 Mercedes-Benz GLE350 by paying an extra $25. It was quite frustrating, but we had no choice. We ended up paying an additional $175 for 7 days. It felt somewhat like a scam because it’s unlikely you'll get the car you actually booked.

Although it’s the most expensive, it’s worth it!

Excellent service. Initially had some issues, but they were resolved well through communication.
