Cons: 1. Rude and unsympathetic staff.
2. Was provided with a 2015 Mitsubishi Lancer whose battery drained while parked on the side of an isolated road in Oaxaca while the radio and emergency lights were on for only 30 minutes. I had to flag a passer-by to start-jump the vehicle, a major inconvenience.
3. The quoted price thru Kayak differed from the actual price by 4.5%, the commission for using a credit card. Aren't most cars rented using a CC? What a ripoff.
