I am aware of the older models being called Newport if they were a 4-door. However, I just remembered knowing a man who owned a '61 Newport in Bakersfield years ago. He was going to give me the car until he heard me telling his Nephew that I would love to drop a 400 and 4-Speed into it. (It had the 3-speed.) Oh no! He'd let it sit since 1973 when he replaced it with a Dart, but God forbid someone try to customize the sitting car!
The car he replaced with the Newport was an early '50s DeSoto; it sat in front of the Newport. He stopped driving some time after the Dart, otherwise....
