Am I Being Unreasonable? Original Owner Wants Car Back

My old cars have always come and gone,,,some stuck around for years, some hours.
I always ask myself if selling, WHAT is a this car worth to ME, and then I ask myself, is that inline with what I feel the market actually is.
Then I ask myself can I stand to list it anywhere at what I know is a totally idiot price like 95% on FB etc, NO I can't !!
