Bernice Wyszynski saw a brand-new Pontiac sedan advertised for "1,395 bananas". So she tried to take the dealer up on that offer. However, the dealer insisted that the car actually cost $1,395. 'Bananas', he said, was a vernacular term for dollars. Wyszynski threatened to sue him for false advertising, and eventually he relented, selling her the car in exchange for 1,395 bananas.
I can buy five bananas at the supermarket for $1. Which means that, in present-day money, Wyszynski got the car for around $280. That's a pretty good deal.
Bernice Wyszynski died in 2003, and the banana incident made it into her obituary
Mrs. Wyszynski became known as the "Banana Lady" after she bought a new 1965 Pontiac Tempest from Stephen Pontiac Cadillac, Bristol for 1395 bananas.
