Sixt may just have a much more vigorous training and procedural habit to find car damage than other major car rental companies but be sloppy in implementation and on making sure with record keeping that they don’t go after the wrong person for damage that occurred prior to the particular rental (or maybe even after the return of the particular car rental).

It’s not just an issue with Sixt in Europe. I have had to deal with this with Sixt in the US too. But in Florida, I was fortunate to have taken a very extensive video of all surfaces around the car except from the underside of the vehicle and of having a video where I was told there was no need to mention the roof thing on the car damage report at pick-up. On vehicle return, however, Sixt in Florida wanted to hit me up for what may have been barely visible branch brush marks on the vehicle roof; but I had a video from before I drove off the lot that even had me point out some kind of weird thin streak look on the roof and that ended the discussion about damage. Who knows if they ever hit up some later rental car customer for that roof condition, but it wouldn’t surprise me with Sixt.

With Sixt, the vehicles are usually nicer on average than what I wore otherwise land; but the service is more iffy and off-putting with the post-return “damage” reports.
