It's okay

Car rental services in the US are highly developed. We originally booked a 7-seater van online, but upon arriving at the Los Angeles branch, we found the trunk was a bit small. They allowed us to choose an 8-seater GMC with a bigger trunk and more space. They only charged us an additional insurance fee of around $150, and upgraded our vehicle for free. During the rental period, we had a few issues: a scratch, a flat tire, and a broken window from a thief. Each time, we called the rental company and they directed us to the nearest service point to replace the car for free, without any hassle. If this were in our home country, it would have been a much more troublesome experience. The service attitude was also excellent. Overall, this international car rental experience was very satisfactory.

Staff efficiency is low, it takes too long to complete the paperwork, please speed up the process; everything else is fine

I booked and paid for the full insurance on Zuzuche. After queuing and handling the paperwork at the store, the staff said there was no Chinese navigation for mid-large SUVs. I asked if it was free, and they said only English was free; Chinese navigation would cost $85 for 4 days. They also said they would give me a good car if I paid an extra $156 to get Chinese navigation for free. Originally, I booked a mid-large SUV, but the store said they'd give me a class 4 vehicle. Zuzuche doesn't categorize cars that way, making it hard to distinguish. They actually gave me a Ford SUV. It feels like even though I paid in full, I had to pay an additional $156, effectively doubling the rental cost. When returning the car, I raised my concerns with the staff, and they only waived $50. So, Zuzuche, please give me an explanation. I called today, but nobody answered, constantly directed to automated services. Please give me a response.

I've only used Alamo at Los Angeles Airport. Self-service car pick-up, no lines, no checking of driver's license, no fuss, no upselling.
