That's easy to answer.
You at once put down your deck quoits and run to the vessel's internet connection. You post on the UKGSer that Eastern European low life scum have assaulted your stable and are in the process of stealing your awesome steed.
At once, a posse of likeminded souls will be formed, drawn from the four corners of the country (and beyond) to race through the twisties (don't do motorways, mate) to right the wrong. Those that cannot join as SWMBO won't let them or because their steed is undergoing wizardry at Hilltop will promise to keep 'em peeled and / or issue dire predictions over insurance wrangles, coupled to demands that the Channel tunnel is sealed forthwith.
Normality having returned, you can return to the deck quoits and that interesting life actuarial couple from Penge, you've been sharing tinctures with each evening at the Captain's table.
