There were upselling services.

Very good overall, smooth experience. They only tried to upsell the highway ETC, which I didn't rent. However, there were few staff members so I queued for over half an hour. Americans work quite slowly.

Not bad

The counter automatically added roadside assistance. Fortunately, there was no language barrier, so I negotiated and it was waived. There were no cars available for the model I reserved, and after waiting half a day, a car came but was reported faulty at the door and needed repairs. A European couple went to negotiate, and they were upgraded without any argument. However, when I went to negotiate, seeing that we were Chinese, they asked us to continue waiting. It took over an hour of back and forth. When I wanted to extend the rental period at the counter, they impatiently told me to call. The additional day was calculated at the full, non-discounted rate, which wasn't cheaper than Hertz. Overall, it didn’t feel very friendly. Additionally, they required a translated driver's license, while Hertz doesn't.

The service experience was poor. I've rented cars from this company twice, and both times, the staff were unwelcoming. One staff member had a perpetually stern face, and another one tried to add insurance quietly. Be sure to check everything carefully!
