Excellent rental car experience for road trip in California.

There are hidden charges.

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 were very helpful, providing guides and assistance for online self-service car pickup.
