Be on your guard. When I picked up my car, I said I didn't want to pay the (ridiculously extortionate) collision damage waiver insurance. The lady at point of pickup said 'no problem at all'. But she added it on anyway. €88 extra. And even that doesn't remove all your liability; still leaves you on the hook for €250 excess. (You can buy your own collision damage waiver from a third party for 100% of the excess for £12). My fault for taking the lady at her word and not checking the paperwork. But they get bad review from me for lying and profiteering.
