Renting a car in the US is the most convenient.

The car rental company wasn't very helpful. When the tire had a leak on the highway, we were stuck for a long time because there was no Chinese-speaking customer service. They didn't offer any constructive suggestions. Finally, I suggested swapping the car at the nearest location, and only then did they agree. Communication was really difficult, but the replacement car was fine.

The car was very new and the service was great.

I followed the guidance from Zuzuche and prepared the required documents, and the procedure was completed smoothly.

I picked up the car in San Francisco and returned it in Las Vegas. Although my English is poor, the rental company provided excellent service. The process of picking up and returning the car was fast and convenient. Very good experience.
