Servus people, the problem doesn’t have to do directly with insurance. But it’s about the question of liability. Since my girlfriend’s sister is on vacation for 2 weeks, she lent me her car (19-year-old Ford Fiesta). On the 5th day the engine stopped while driving. According to ADAC-Mensch the diagnosis is: most likely engine damage (engine clamps) We informed the vehicle owner by phone. It is of course fixed and finished. Now the best.. . Their parents (they went on vacation together) think I should be on the line for the damage. However, my opinion is that the damage is due to wear and tear after all, the car is no longer the youngest. For this reason, the engine would sooner or later have failed with *any* drivers. I would like to try to support the vehicle owners that they get a replacement car as soon as possible. However, I do not realize that because of the damage I have half (!) zah I would like to hear from you the opinions. I would also like to know what the situation would look like if a customer had an engine damage in the case of a rental car? Will the customer then be liable? Would any insurance (liability) pay for it? I think no, because it is a wear part (engine). Thank you! Flea
