You know, Ronald if you buy a car and the person selling it to you does not have good title, that it can be confiscated, even years later. It is stollen goods. It doesn't matter that you didn't realise you were doing something wrong years before.
That's why it's up to you to ensure that the person selling the car to you does have good title to it.
Okay, it's distressing, but it never would have happened if you'd taken the necessary precautions in the first place.
