So me and the dudette went for a lovely trip to Tassie over Xmas and new years. We hired a car. The roads are stunning. Definitely need to return with a bike. So the day after we returned the car we get a phone call. "You've scraped underneath the rear wheel arch, we are charging you $3000 excess and you will be refunded any difference, we'll send some happy snaps". We think there is some bullshit damage to the undercarriage that should be classified as wear and tear. We weren't aware of any damage and we looked pretty closely. 3 weeks later not a peep. I call today and they send me some thumbnail sized photos where there is some reasonable damage on the rear bumper. Damage we would have seen. The only rational explanation is that it was hit in the car park lot after return by another car or an airport trolley. That or we didn't see some pretty clear damage when we were looking. We were standing on this corner of the car when we got the receipt from the return guy. The damage wasn't reported until 11:30 the next day some 18 hrs after return. A) if you return a rental car ask for it to be inspected there and then. anything I can do?
