Cons: Your site misrepresented Hertz--saying that they would take credit and debit cards (I don't have a major credit card). Hertz rudely said they wouldn't honor that, so I had to figure out another plan the day I was leaving on a vacation that had been planned for two months. Budget figured out an option for me the same day.

Inconvenient Pickup and Dropoff

Pros: I was given a comfortable, clean Subaru Crosstrek.

Cons: Pickup required a shuttle from the airport to a local hotel. There was only one Hertz agent so the wait in line with all the other folks from the shuttle was LONG. When I returned the car there was the same lengthy wait. Then I was denied a receipt because I didn't know the mileage. I was on unlimited mileage and no one had told me I would need to report it back. The agent said this was for their maintenance purposes which has absolutely nothing to do with me and doesn't explain why I couldn't get a receipt. If I fly back in to this airport again I'll use a different rental company.

Saved money away from the airport, got taken on gas

Pros: Saved airport fees by renting at non-airport location. Got a free upgrade from Kayak/Hertz too. Toyota Camry was the perfect size for 3 adults, kids and luggage for 10 days.

Cons: Car was not cleaned well inside, stains on driver's seat and carpet. Got taken on the gas refill by Hertz, it was not clear to me that I was buying a full tank of gas at $3.09, therefore any gas left in the tank I had paid for and didn't use.I thought i would only be charged for the gas to fill the tank when the car was returned. Rental companies pay commission to employees for selling extra insurance and services. I should have known better, just fill it up and return it on time.

Cons: I was charged $13 plus for a second driver per day, no one mentioned that when I picked up the car, nothing to initial, nothing at all instead of paying $145 for the time I had the car I ended up paying $269!

Not enough cars available

Pros: Car was nice

Cons: There were not enough cars available when we arrived. It was after midnight and some people arrived and were told sorry no cars even know they had a reservation There was no offer to find a car with another agency, and there were several still open. We were left to deal with it ourselves saying “that’s just life roll with it.“

Horseshit

Pros: What was promised.

Cons: What was delivered. Reserved a full-sized sedan ("Chrysler 200 or similar") but they wanted to give me a mini-van and call it an "upgrade." This, of course, would would be a less agile vehicle that cost more money to fuel. I felt pressured to accept these horseshit terms, and so I did not take delivery of their offer. Another car-rental agency was able to provide an acceptable vehicle for $90 less over the roughly 68 hour rental period.
