There was a story many years ago, and I don't know if it's true or not. A customer had a car with an odd rattle. It had been back to the dealer many times, but no one could find the source. Eventually someone cut open a sealed section of the body. Inside was a steel nut hanging by a string. Along with it was a note that read "Bet it took you a long time to find this".
I hope you have better luck.
