I would not recommend Fox rental car to friends I know. But I will recommend it to anyone I hates.
I tried Fox rental car three times in the past two years. Once in San Diego, twice in San Francisco.
The customer service in San Diegois terrible. The waiting for the shuttle bus is very long even in a sunny afternoon. The waiting line in the rental office is very long. Also the representatives are very rude. So we canceled the reservation after talk with these rude representatives.
The customer service in San Franciscois better. The waiting line is very long too. But the representatives are very polite. But the thing we do not like Fox rental is they have a lot hidden traps. They are sharing your private information such as credit card info with some other 3rd party companies without your knowledge. If you have a parking ticket, even if you paid the ticket, the 3rd party companies will try to charge you 40$ service fee. So we stopped using Fox rental car service.
