Have you booked a car from Chilean Rent a Car? Unlike the other car companies what appears as US dollars is in fact pesos and the the point is used as a comma not separating dollars and cents so when I saw a week booking for a cheap car at $215.56 I thought that was a good deal (car rental is Chile is not cheap). However, when it came through on my statement as £300 I realised it was the most expensive car I'd ever hired. Not only that I could have bought the car for that price. It had no suspension and 80,000k on the clock and the tyres were cheap although I presume road worthy.
