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

The car is new and quite good.

Dollar's service is good, convenient, and offers competitive prices. However, the counter at San Francisco Airport is very crowded and slow, requiring over half an hour of waiting.

The queue was extremely long.

Like: The car, a Ford Fusion Hybrid, was an excellent, well-designed and maintained piece of equipment. Great car. Rate did not match the reservation rate (it was higher, due to "taxes and fees", but was quickly corrected, once I showed the printout and e-mail, which did include taxes and fees.
Dislike: That the rate was higher than was what was contracted for. Fortunately, I had printouts and e-mails to prove it.
