Thrifty overbooked their rental cars

Convenient

Overall, I'm quite satisfied. The car was in great condition, it was a new model X3 with strong power and quick acceleration (probably because the car is relatively light). The onboard GPS was very useful. Important to note: The counter staff will still offer additional paid items such as insurance and prepaid fuel. I had already purchased insurance when I rented the car, the likelihood of needing glass and tire insurance is low unless you are in an area with poor security (like an incident near my home where a car window was smashed and robbed). Generally, you don't need it, especially if you're staying in a hotel. Prepaid fuel is also unnecessary; many gas stations are cheap, and it's unlikely you will use up a full tank right when returning the car.

The staff at the car rental company took advantage of Chinese tourists' limited English skills and set multiple traps. It was really bad.

There were quite a few people, but fortunately, the car rental service counters at San Francisco Airport are numerous. A short wait was all it took.

They tried to sell extra insurance at pickup. Make sure to carefully check for any additional charges before signing. Just insist you don't need it, and it will be fine. The car's condition was good, it was a fuel-efficient, lightweight Japanese car, and the speed was decent. Returning the car took only a minute.
