Their business model is simple: at the end of the rental agreemnt they will find any type of scratch or dent they know is not on the check-out report and charge you for it claiming it was you since you have no way to prove. My advice is take photos of every single inch of your rental vehicle. But to be honest I would avoid them at all costs. They are functioning as a scam. They do not have any single customer support only roadside assistance (and even that is bad). Unfortunately, they are ran independently by a lovcal franchise called Helvetic Motion AG. Global or regional headquarters will wash their hands out of any problem you may have with them. AVOID!!!
