Painful experience. Up sell for insurance, prepaid gas, GPS was amateurish and unyielding. Nothing like getting a lecture on insurance and Arizona liability law from a high pressure sales person disguised as a customer service representative. Finally had to ask them; "please do not ask me the same question again".
More, there were no other customers at the service desk and it still took them 20 minutes to process my reservation. In fairness to Fox, I am frequent renter at PHX and Dollar and Thrifty are just as bad. Enterprise is usually pretty good but their rates tend to be higher.
