Overall, I'm quite satisfied. The car was in great condition, it was a new model X3 with strong power and quick acceleration (probably because the car is relatively light). The onboard GPS was very useful. Important to note: The counter staff will still offer additional paid items such as insurance and prepaid fuel. I had already purchased insurance when I rented the car, the likelihood of needing glass and tire insurance is low unless you are in an area with poor security (like an incident near my home where a car window was smashed and robbed). Generally, you don't need it, especially if you're staying in a hotel. Prepaid fuel is also unnecessary; many gas stations are cheap, and it's unlikely you will use up a full tank right when returning the car.

I booked a sedan but was strongly pushed to upgrade. When I resisted, they gave me a hatchback, claiming that the model I booked was unavailable. I ended up with a Ford Focus hatchback, only to see the model I had booked right next to it in the parking garage.

Because we needed to install three child seats, we initially requested a vehicle with foldable rear seats. Upon picking up the car, we found that the trunk was too small to fit two suitcases. The rental company immediately provided a car with a much larger trunk. Very satisfied.

There were quite a few people, but fortunately, the car rental service counters at San Francisco Airport are numerous. A short wait was all it took.

I needed to extend the rental by a day and when I called in the first agent told me it would triple my rate. I declined as I still had to confirm I needed it and when I called back in they were able to honor the original promo price. Seems a little scammy to me or uninformed agents. Other than that I got a great deal on the car and it was a nice vehicle.
