Mark,
What wonderful piece of research or a wonderful personal knowledge of these cars!
The one that my dad was supposed to buy did not have a glass divider, but in my kids mind, I do remember the car seeming a bit stretched, so it must have been some kind of a limo.
I do think I distinctly remember my dad taking it over 100mph on our test ride. Would that have been possible; I have always used that example as my first trip past the century mark.
My second trip past 100mph came when my dad bought a 1960 MGA. His cars between the Cadillac test drive and the MGA were a 4cv and a Dauphin meaning that I rarely saw 55 in my formative years.

Later, a couple of clear, plastic tubes rose up along the C-pillar to direct the air into two plenums on either side of the roof, above the headliner. 4 (Series 62, 60S) or 6 (Series 75) chromed vents then passed the air into the passenger compartment; the forward most vents strategically placed so as to freeze the front seat passenger's necks. The controls were mounted in a little add-on pod placed under the center of the dash. There were knobs for temperature and fan speed, with an "Off-On" switch between them, all finished in brushed steel to match the rest of the switchgear.

It wasn't until 1956 when AMC (with the help of it's Kelvinator division) introduced a much lighter, simpler version of A/C that the evaporator moved into the firewall area in the dash, thus making A/C a possibility for small cars (and convertibles).
