There was an article in The Age saying that Europcar has been incorrectly charging people for pre-existing damage to vehicles. (Not the first time I have heard that).
Just a reminder to people to document the condition of their rental vehicle before driving off (I think this would be particularly important if renting moving vans, they are often pre-banged up). When we were in France recently we photographed the rental car from all angles and took a close up of existing scrape marks before we drove off. We were with Avis and we had no issues with them.
I'd thought that was common knowledge. Usually I do a walk-around video of the car before I get in (so you can see it's still at the pick up lot), close-up photos of existing damage, and obviously make sure any significant damage is circled/listed on the condition report.
That's a given with renting any car or other vehicle (hell, even leasing a property is the same).
