I had a new 1975 Plymoth Duster and can relate to that seller. Although I think I paid about $4500 for it new. I can't imagine why anyone would pay $3000 for it 35 years later. In retrospect, it wasn't worth $3000 new. It had a new invention: self changing oil. All you had to do was add a quart every fillup and change the filter every 5000 miles.
