Hi all, So this is a grey area and I really do not know how to go about this so I would appreciate any input here. I'd rented a car for the weekend to drive around town and visit nearby places. Had some time left before returning so I had a colleague over, and we decided to go out but he wanted to take the wheel. So, we drove to a nearby restaurant and while parking into the restaurant he backed too heavily and banged into the wall. There is a sizeable damage to the car's rear with scratches all around, damage to the rear lights and the bumper too. I know I am screwed as it is the worst car rental company (Sixt), but also, I was not driving. I know my card, Amex has an insurance that covers this sort of stuff, but of course it requires me to be the authorized driver to be able to claim this. I do not know what to do here, because I do care about the colleague and don't want him to get screwed because of the charges too because I know it is gonna be hefty one (probably a couple thousand bucks to say the least), so any advice would be appreciated here. Do I trust the claim verification process to not involve checking through on the cameras, or, just be honest, I don't know. Help!
