What can be done against vandalism?

Hello dear forum. I have already read and heard a lot here. Always some expensive cars are scratched. Out of envy, out of hate or why. Well, what if someone wants to invest a nice car. 80,000 € any new Porsche or something. This person has no private property and parks on the road. Now come some full-fledged and destroy the car. Scratch everything, kick in everywhere, hit slices, bite the mature, chop with a m hammer up and everything. Damage : we say ma 10,000 €. Yes, now the owner has bad luck because he drives such a car or what can you do now? Extensive? But then you have to pay a partial amount yourself. There is no other form of insurance to compensate for car damage. So especially vandalism. That you can bring the car back to forderman for example 2 times a year. Just unfair, because you are afraid to get a nice car. A garage is nice and good, but not You always park there. Sometimes you forget it, or you park somewhere else with relatives or friends on the public road. So how does an 80,000 € car owner protect himself?
