I recently used this company to hire a car. When I arrived at the carrier company, they refused rental cars insurance and told me the option was leave a 1000 euro deposit against any damage or buy their insurance. As they wouldn't release the car without fulling one of the options then I paid a large sum of money extra. Rental cars.com came back to me after I complained and basically fobbed me off. Go direct to the hire companies, it's cheaper.
