Hi Moossafa,
It depends on what the buyer would like to do. There's a couple of options:
#1 - The buyer comes to view the car on the island (there's flights from all major UK airports or there's the boat) and they can take it back on the boat with them.
#2 - I can place the car unoccupied on the boat which will take the car to Heysham / Dublin / Belfast and the buyer can collect or arrange pickup from there. I'm happy to give a video tour of the car or something, if the buyer wanted to purchase unseen.
It's fairly straight forward - but I appreciate it's another step in the process.
Cheers
