The queue was too long, and the service experience was very poor. At San Francisco Airport, it took 1.5 hours to handle the paperwork and another half an hour in line to pick up the car! The car model felt much smaller than what was reserved, but I couldn't wait in line any longer.

Excellent. This trip was cut short due to my mother's health issues, but the car rental and driving experience were very good.

It was okay. The queue was relatively quick. They initially gave me a Korean car, but I was not satisfied after picking it up. They immediately helped me switch to another car. However, the staff seemed to be South American and their English was not very good, so communication was difficult.

Average service, a long wait because the staff spent a lot of time recommending various services, and the paperwork did not match the actual situation (discovered later).

Would not use Dollar again. Alamo are better. The car had a built in Sat Nav which they didn't advise us of so we paid for extra for a Sat Nav at almost $10 a day including tax which we didn't need. Got stuck in traffic so returned the car 2hrs later than specified and ended up paying for another day hire.
