There were a lot of hidden costs that we were not informed about upfront, including a mandatory €1000 deposit if we didn't pay out for the extra insurance cover, and a €102 fuel deposit (which is more fuel than will even fit in a Fiat 500). Staff also didn't tell us about these costs in one go, even when directly asked 'what is the total we will have to pay'. This created a really negative experience for us and impacted on a lot of our holiday plans. It seemed like this was intentional, a way of forcing people into paying money without giving them the full information in advance, and it felt like we were being scammed. It was also contrary to the information that we received from our broker, Easyrentcars.com, which advised that we could be charged a maximum deposit of up to the equivalent of $500, meaning that we were missold this car hire deal. In future I will avoid Interrent and recommend that others do also.
