This company engages in classic fraudulent advertising. They tell you the car costs like $7 or $10 USD per day - which is a great price! As my personal auto insurance provides coverage while renting cars, and as my personal credit card also provides coverage, I do not need to purchase duplicative insurance from the rental company. When I went to pick up the car - which is located about a 25 minute ride from the airport in Cancún, by the way - I was informed that they had to put a charge of $8,000 USD on my credit card, for the full value of the vehicle. I agreed. They then "attempted" to charge this on my card but they said that the charge was denied by the card issuer. Standing in the rental agency, I called the company and inquired about the issue, and they told me that no attempt to charge even this ridiculous amount of $8,000 had been made. The vendor then tried to to negotiate the price of the insurance with me - which I again denied. It seems that the company does some sort of trick to their credit card machines whereby it spits out a rejection slip (LIMITE EXCEDIDO), without ever attempting to charge the card this money. Then, when the car rental people tell you that the charge cannot go through, they offer you a reduced price for the insurance. In short, the low prices that are advertised are not offered. This company will NOT rent you a car if you do not purchase their very expensive, and in my case, entirely unnecessary, insurance packages. I will submit this comment to PROFECO - the Mexican Government Agency that defends consumers' rights - for further action on their end.
