Hello Graeme! Your '59 Savoy is in “From Russia With Love”, included in this post. I have many such '59 clips in Windows proprietary “wmv” format on my old website, waiting to convert to mp4, the web standard. But I’ve converted this one here for your enjoyment!
Because the Savoy is a four-door, the roofline does not slope as it does in the Sport Fury or other two-door hardtops. Four doors came in two flavors - sedan (like the Savoy) and hardtop (e.g., the standard Fury). The chief difference in body styling between the two is the lack of a “B” pillar, or separation between doors at the mid-section of the car on the Fury, and example of which you can find here. But even the four-door hardtop’s roof does not slope like two-door hardtop.
I hope you enjoy the movie clip. And I’ll ask others here to comment on your inquiry. Good luck!
