風吹けば名無し

You have requested change of the main driver on your booking and this will involve changing the whole booking
(making a new one) and currently the car you have booked is no longer available from the same supplier as availability and all prices are live and they change on a regular basis.

I would be grateful if you could get in touch as soon as possible to confirm if you wish to proceed, as the alternatives we are proposing are subject to change.
