What is the maximum excess amount in the event of a claim?

Depending on the car category, the maximum excess amount per damage event is a mere €50 (category A, B) or €125 (other categories).
The renter has a maximum excess amount (deductible) in the event of financial damage which the car rental company cannot recover from a third party. Apart from damage by fault of the renter, this also refers to windscreen breakage, repairs to tyres, theft, vandalism, loss of car documents, etc. The exception is loss of the car key and refuelling with the wrong fuel in which case all costs are for the renter.
