I booked a car via economybookings.com by phone with a pick up at Marseille airport, the car was supplied by Sixt. It was my first time when I booked a rental thru such a website so I needed a consultation and manager that I've been speaking to gave me full info on my rental opportunities, additional options and explained a booking procedure. Thanks to it I knew in advance everything about the fuel policy, whether it is necessary to buy an excess insurance or not (I bought, they provide their own) and other special aspects. At the rental desk I was told exactly the same that economybookings.com manager already explained me. I got almost new clean car and even received an upgrade and as a result had a great smooth rental.
