Since our friend didn't bring a translation of their domestic driver's license, we had to purchase full insurance at the rental office when picking up the car, which ended up costing more than the rental itself. However, they did upgrade our vehicle. That said, three months after returning the car, we received a 40-euro speeding ticket, and the rental company directly charged us a 99-euro administrative fee. This fee is extremely unreasonable, and it was included as an addendum to the contract after signing. Apart from passing our information to the traffic authority, the rental company provided no additional communication and deducted a management fee that is clearly above market standards without our knowledge.
