It is simply a rip-off. These people are thefts. It is a shame on kayak and especially shame on this company what they do. We booked a car for 260 usd and they forced us to pay at least 680 usd (with limited insurance), or 730 usd with full insurance. They cheated on everything: the insurance price (300+ usd for a week?? I pay 300 usd for a year with my car at home..), the fx rate (20% vs 2-4% which the banks actually charge), and they even wanted to cheat on us with a fake damage (luckily we took pictures carefully). Disgusting service, they should be heavily penalized in a normal country, they couldn't do it in Hungary or in the EU.
