Thank you to all.Yes,it's the recently acquired car and I am searching for a transporter as it has not been driven since a long time and I think that it's better to check it before to drive it.
I will give some calls tomorrow. (it could be useful to some of yours to know that we could ,in the past time ,have our cars carried without a driver from Plymouth to Roscoff by Brittany Ferries.It's over now (for a matter of insurance,allegedly)
Indirectly it probably is insurance led by the fact you don't want an unaccompanied private vehicle on a vessel without the owner, it's a way some terrorists used to operate by booking a vehicle on with timed explosives inside whilst they stayed ashore.
Good luck getting her back home.
