To combine the Harley and Door examples. In reality, the person breaking the glass should have just paid for the glass. Problem solved. It's all the homeowner was owed or entitled to. But, to help ease the situation, they agreed to pay for a new door. I think they'd get the old door if they wanted to pursue it. Like if I backed into your Harley and damaged some stuff and because I wanted to make things easy, I decided just to buy you a knew one rather than pay for fixing what was broken. I find it highly unlikely a court would side with the owner in keeping the replacement and the repairable original. I wouldn't pursue it for a door, but if I wanted to, I have a feeling the courts would also rule the owner owns the replacement, they don't own 2 doors because legally, all they were entitled to is new glass, not 2 doors.
