The car I rented had some issues with Apple CarPlay not working properly at times, but everything else was great.

There's a quick rail system from San Francisco airport to the car rental point, which is very convenient. However, the car return location at Los Angeles airport was changed and there was no notification, so it was impossible to find the place based on the address given in the order.

Excellent. Rented cars twice in Honolulu and Big Island. The entire pick-up and drop-off process was smooth and convenient. The airport shuttle bus was also very handy. We did not encounter any mandatory insurance up-sells as mentioned online before; the staff was very good. The price was reasonable, the service was great, and the car condition was very good. Highly recommended.

The rental staff was very friendly, but they tried to upsell too many extras, so it's important to stick to your own decisions.
