Found a cheap transport trailer for rent at a for sale site in Ireland
here and its under €40 euros which seems reasonable, more reasonable than I was expecting. I need to contact them though to find out their location and whether its big enough to transport a bulky Bentley. If that doesn't work out then I suppose its either buy my own, which seems a little expensive for one trip, or just get a company to transport it for me. Going to try and get some quotes to see how much more it would cost to get someone to courier it for me.
