Hertz in Cancun practices and interesting and sophisticated fraud. I reserved my car online at a price of $169/week. However when they wrote up the contract, they wrote the price up in pesos. I asked what the price was in dollars, and using a calculator they showed me that it was $169. However, when I returned the car I showed them that based on the current official exchange rate of 13.5 pesos to the dollar(essentially unchanged for the week that I was there), their rate came out to $188. They responded that the exchange rate that they use is 15 pesos to the dollar. However 15 pesos to the dollar has not been the exchange rate for a decade--it was pure and simple fraud. Moreover, it is a sophisticated fraud because most people think that they're getting a good deal because the exchange rate looks better than actual.
