Overall pretty good, pickup and drop-off were very fast.

I booked and paid online in full via the Zuzuche website, but when picking up the car, AVIS staff tried to add extra charges which I declined. They were rude and secretly added a service fee. I've been coordinating with Zuzuche customer service for almost two weeks, and it’s still not resolved.

The additional driver didn't have a credit card, and they wouldn't let us pick up the car at the airport. Later, we managed to use my credit card at a city office. It was a bit troublesome.

The queue was very long, and they tried to upsell too much.

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.
