I had booked my car through economycarrentals and found a really good deal when compared to other websites. I was worried when I read some negative reviews but apparently all went well when we went to take our car at San Frans downtown. I have further booked 2 vehicles for a day trip for my colleagues and all went well. Just a note that road side assistance is not covered for in the package and the car rental co will ask if you wish to add that in.
