It doesn’t work like that in the UK, no accident will be recorded on the car. The OP is spot on here, it’s a car, old people are always more likely to have these types of bumps. I’d explain to him that’ll need to be an insurance claim and get it to the Porsche garage so they can book you in and his insurance can pay for you to be in a nice new 992 whilst you wait on yours to be repaired.
