The price is relatively high. They told me that if I didn't purchase insurance, any damage would cost 2000 Swiss Francs. I'm not sure how they calculate this. I initially planned to return the car on December 31, 2018, but the store was closed that day and no one notified me in advance. This left me in a difficult situation. Thankfully, a kind person informed me that I could return the car at the airport location, which saved me from missing my flight.
