Believe me Tomek,actually there are!!!Not only Porsche cars but also other expensive brands.I was in the Insurance business until I retire a year ago (I was running my own office) and I know first hand!You'll be amased by what some of them was asking in order to be able to achieve the lowest premium possible!!Honestly I don't get these videos.
I don't think people buying Porsche vehicles drive it without an insurance, many buy extended warranty so you really don't care how much the repair would be, especially in case of damage covered by insurance
