A number of years ago, my 15 year old Ford Escort was rear ended.  And while the damage wasn’t too bad, it did ruin the rear bumper.  Thinking that it would be an easy fix, I called a local salvage yard.  Yes, they had one and it would cost $300.  I told them that I just wanted the bumper and not the whole car.  Eventually I went to the lumber yard are purchased a 2×12 for $10.
