Definition of insanity - RE: Pioneer Car Radio - $20 (InsanityVille)

This craigslister has been posting this car radio to craigslist for over 5 years.
A twenty dollar car radio that hasn't sold in over 5 years.
Most people would come to the conclusion that the radio is a piece of 💩 that nobody wants and throw it in the trash.
Not this craigslister.
Perhaps persistence is a virtue? I don't know.
If it was my radio, it would be rotting away at High Acres by now.
Maybe hold on to it for a few more years, list it as "Vintage", and ask $200 for it?
