Do not use Sixt. Whilst their check in procedure was fine on returning the car they discovered minor damage to a wheel rim that they claimed was not there when the car was collected After much correspondence to no avail they charged my credit card for the supposed damage and an administration fee As it happens I had a photo of the rim on pickup that showed minor damage already there . The photo was taken to show an existing large scratch above the wheel arch and consequently the rim which was included in the photo was a little fuzzy but still legible Not accepted by Sixt and all further requests including asking for a copy of repair invoice ignored Reported to ECRCS and my insurance company So use at your risk
