Very satisfied, just waiting for the pre-sale fee to be released.

Great, the car was in good condition, quick and convenient.

I encountered an unethical staff member at Avis who seemed to be a manager—an outright scammer. Here's the story for everyone to understand. Avis requires the tank to be full when returning the car, but due to heavy traffic, a 40-minute drive took two hours. Worried about the time, I decided to refuel near the return location. To my surprise, there was no gas station nearby (which is unreasonable because if you refuel far from the return spot, the tank will not be full by the time you get there). For everyone's information, the return location has a gas station, but the price is $10 per gallon instead of the normal $3 per gallon. So, we were fined $61. Isn't this a deliberate rip-off? That's not all, though. The worst part is yet to come. We tried explaining to the staff to avoid the extra charge, but if it didn’t work, we were ready to pay. The staff introduced us to an American man who seemed to be a manager to resolve the issue. However, this 'scammer' pretended to help us. He printed a receipt, intentionally showing a charge of 61 and then a -61, making us think the fee was waived. He also added a charge of 17, supposedly for the regular gas price. We trusted him without thoroughly checking the contract filled with English and technical terms, and thanked him repeatedly. Later, I found out I was charged on my credit card. Upon inspecting the receipt, it all became clear (I kept the receipt just in case). The $61 was not a big deal; we were ready to pay but just tried our luck. Who knew people in the U.S. could be so unethical? Even when we picked up the car, the front desk staff was unfriendly. Maybe it was due to the cheaper rental rates for Chinese customers through Zuzuche? On a positive note, the customer service at Zuzuche was excellent.

The cars from Avis in San Francisco are not very new. When I went to pick up the car, they informed me that the reserved model was not available and gave me a very old Ford instead, claiming it was the only similar model available. If I wanted to change cars, I had to pay extra. I saw many similar models at the pickup point, but after checking and returning to the counter, they still insisted it wasn't the same type and that I had to pay extra. The attendant was Chinese and tried to overcharge me just the same. I thought a big company like Avis wouldn’t have such issues. Finally, after arguing with the manager, they gave me another car, which they claimed was an upgraded Ford Explorer.

Convenient and fast, good quality cars that are relatively new, and the car use instructions were explained patiently. However, it is still advised to adapt to the car a bit before hitting the road.
