Cons: The upsell was not tactful at all. When the employee pressured me to buy the optional insurance, I kept asking "how much is the insurance" and she would only tell me the total (not the additional cost I was incurring). I asked repeatedly and she either didn't comprehend the question or chose to ignore it. Then she told me I could elect to return the tank empty and Hertsz would just charge me for whatever it cost to refuel. But in fact I was charged for a full tank of gas right then and there. I could have saved myself at least $10 by just refueling myself before I returned. Lame.
