Merci pour vos réponses.
Sur le site europcar.is, dans les conditions je viens de tomber là dessus:
- Debit card(s): Debit card(s), that are not associated to a bank account, are NOT accepted at time of booking or at the time of rental except:
- "Maestro" cards issued by UK banks and for customers renting in the UK
- "Visa Electron" card(s) that are accepted for online payment on some country of destination (Please note however that customers who do not possess any other credit card in addition to the "Visa Electron" shall ensure their account holds sufficient funds for the deposit to be charged at "Check-out").
Ca semble bon pour la carte de debit, même si c'est pas dit clairement.
Je vais finalement prendre une carte dit "crédit" le temps du voyage, la peur de se retrouver "bloqué" le jour J est trop importante.
