Car was given to me with less than 1/8 gas in the tank. This makes it impossible for me to return it with that same amount unless I was driving it down to empty which is of course irresponsible. If you’re going to be so strict on gas policies it needs to go both ways, give me a car w a full tank so I can return it to full and bring it back, instead I’m sure the person that brought it back so close to empty was charged for it and I was “charged” by of course having pretty much no choice but to bring it back fuller. With gas prices as they are this is a burden, and I’ve never been given a rental car before with an almost empty tank. I’m a frequent renter at this location but this really makes me think twice about where to rent next time.

When I went to pick up the car, they had 14 reservations for zero available cars. No warning beforehand, I had to come up with a new plan to rent a car somewhere else on the spot.

+ Very fast drop off. + Good price. + Pleasant agent. - Low tire light was on but they said that was normal and didn’t do anything about it. We added air ourselves. - Very confusing and costly half-full-tank plan.
