Commander 57
1960 Plymouth sedan used as a taxi cab in this episode (3-12).
The "Fleet Special" was a de-trimmed Savoy sold for commercial use.
(Note lack of chrome spear on rear door.)
Model code was still 41, the same as Savoys.
This car was briefly ridden in by the main character (until the cab driver fell over dead due to a jungle curse, that is!)
