I have looked at my car insurance the last few years. If I calculate this, I get about a tariff premium increase of an average of 4% a year. I know of my residential building insurance that there is a construction price index that takes into account the rising construction costs. What is this in the car market? What is the cost increase real on the market? Sometimes quite rough out what I mean: A VW Golf cost 20 years ago e.g. 20,000 DM. Today a VW Golf costs 20,000 Euro. On the one hand it is due to normal inflation, on the other hand it is also due to the fact that the cars bring much more equipment with them. Thus it is also clear that the insurance companies have to pay more in case of damage. So can one say here what increases in the car market on average last year/years?
