Hertz

If I could have left 0 stars I would have. The vehicles are reliable but their customer service is the worst I have ever experienced. They are unable to help you solve problems involving their vehicles, or for that matter, help you find a satisfactory solution.
While the rates are slightly better than other car rental companies they will still get you with the mandatory insurance coverage, regardless of whether you plan on using the one your credit card company offers or if you already purchased one through a booking site. According to the company all other insurances, besides theirs, are null. Also, be aware that the coverage offered to you is based off the car msrp, not the claim value.
During one of the nights I was Mexico City I was involved in a car accident, not knowing what to do I called Hertz customer service for help. It took me 8 hours to get a hold of someone! I was able to get another car for the reminder of my stay and was told that the invoice for the damage would be ready for me at the scheduled return date.
When the return date came and I asked for the invoice I was told that it was locked in the manager’s safe, whom wasn’t scheduled to be there for another 3 hours. By which time I was supposed to be on a flight back home. Thus, I wasn’t able to get it but that I could be sure I would be charged for the «fair» amount incurred to the vehicle.
A week later when the charges cleared I was charged a ridiculous amount for a new bumper. For a whole month, I tried getting an invoice for the damage but they simply couldn’t find it.
Next time I visit Mexico City I will rather walk than rent from Hertz again.

No respetan las reservas y solo dicen que es politica de la compañía y cambias las reglas cuando uno llega a la reserva. No lo recomiendo.

I tried to rent a car from Hertz on line and the web direct me to a phone number that answered as Hertz and took my reservation. Immediately, with in seconds I redialed the same phone number to modify the reservation and they told me to do it when I picked the car up. When picking the car up they would not modify the reservation and told me to call a phone number to make the modification. I picked up the car less than an hour ago. They would not modify on the phone and said I had to do it at the pick up station. I will make it work, but am dismayed that Hertz has been unprofessional and essentially jerks in this instance. I will not rent from Hertz again. In France or in the USA.
