If you're traveling in San Francisco and not in a hurry, there's no need to purchase Fast Track.

Overall very satisfied.

The staff will try to upsell various things like insurance when you pick up the car. They exaggerate a lot, but you can ignore them all as it's completely unnecessary. If you have a friendly face, you likely won't get the car model you reserved; it will be much smaller, and there's currently no solution for this.

The category of car booked was not available and had to pay extra

Rate was not very beneficial for the car I got

Excellent car and staff.

It would have been nice if all the extra charges were clearer up front. The total at the end was over double the advertised price.
