Please avoid because the quotation they send you is not what you really have to pay at the desk!!!. Hereunder my story. I booked a car through AirportRental: 10 days car rental with ACE company at Cancun airport with the maximum additionl insurance, the so called Protection Plus. Total 260USD+120USD=380USD. When I got to ACE desk @Cancun airport I was told that, by law, they could not give me the car without one of these two additional insurance: - Basic insurance: 220USD (189USD + VAT) - LDW2: 324USD (279USD + VAT). I decided for this, the equivalent of the Protection Plus I have already payed to Airport Rental. Moreover I had to pay additional 60USD for an Airport fee! Obviously none of these expenses were in the quotation I had received and booked from AirportRental!!! After approx 20 emails and 2 months with customer service AirportRental gave me back 120USD of protection plus and 60USD of airport fee. So at the end of the day I spent (approximately) 380+324+60-120-60=584USD instead of 380USD! I don't think this is correct.
