This is an insurance policy that covers the car's bodywork in the case of a collision. However, be very careful as it only covers the bodywork, so there are loads of areas of the car that it doesn't cover such as windows and mirrors, tyres or wheels, the undercarriage of the car, lost keys or damage to any of the additional gadgets you might have rented such as a GPS device. It is a basic coverage package and is available for almost every vehicle for hire. KAYAK website does indicate which cars do have it in place already and which do not, so be sure to check when picking the ideal car for your trip. Search car hire on KAYAK
