American/Caribbean Car Rental in Cancun is engaging in a credit card scam. Don't make the mistakes I did:
1) Don't sign a blank agreement to pay for damages. After we delivered the car in fine shape, they filled in the blanks and charged us for non-existent damages
2) Don't let them bait-and-switch--especially without getting the exact cost of the crummier car they give you. Instead of the SUV we reserved months in advance, we got a car whose ignition wire jiggled loose. To their credit, they came and fixed it, only to charge us many hundreds of dollars for this service we were told at the time was "free."
3) Don't sign ANYTHING without getting an exact accounting--which means that you will need to arrive at their place WAY before your plane is due to leave. Rather than miss my flight, I signed and departed based on their promise I would get a full accounting
4) DO NOT USE THIS COMPANY. I, in fact, will not ever be returning to Mexico
