Pure luck.
Talking cars at a new job back in 2003, and one of the guys knew of this car and knew the family that owned it for years. It sat in the dealership in Holdrege, NE until 1984 when the owner passed away (I have pictures supporting this). One thing led to another and a week later I went to Texas to pick it up, with 6.9 miles on the odometer. Show car trailer queen since 1984.
