what to lose ...BOV....or your life ?

I think, once things get to that stage, a four wheeled vehicle is more a liability than a tool anyway. Good to have one to hand, but it is more likely to get you killed than to save you.

Unless there are a lot of you well armed, let it go and then curse yourself for having it parked in such an obvious place. Then go round the back and oil up your mountain bike.
