Hi everyone, thank you for all your responses, we're one step closer to cracking the case with further intel - As Captain Kernow advised, we had a look into the tax details through the DVLA website and the vehicle is both taxed and insured. Whether that gives anything away in terms of criminal activity, an owner just going on holiday or local garages using it (although, I'm not sure where the nearest garage is that would supply Bentleys - anyone any wiser?), we're unsure. Might be worth waiting another week before contacting police because it is suspiciously snazzy (less so with bird droppings now though) The saga continues...
