You can only extend a rental. Find out more about the extension. You cannot change the number of kilometres provided for in the contract or advance the rental starting date.
If you want to add kilometres, you can simply pay the owner the extra kilometres travelled at the end of the rental.
If you want to start the rental earlier, it is necessary that you cancel your booking in order to submit a new request to the owner with the corresponding dates. You can also proceed to a second rental request which would take place before the first one.
In case of need, please contact us at 01 53 40 95 35 from Monday to Friday, from 9:00 a.m to 9:00 p.m and, on weekends and holidays from 9:00 a.m to 7:00 p.m. You can also get in touch with us via our contact form.
