What made the Scamp / Swingers special

The Scamp/Swingers were a sub model that was easy to order and popular with the public. They had the appeal that the more plain models didn't have. Same with the Road runners and Super Bees. Much more fun than a Satellite or Coronet. Although from a collectible/production standpoint, fewer stripper models were made with the trim and powertrains of the hot models.
