Sourced production or model lifecycle range used by the main catalog timeline.
ChicagoInterchangeable-Body Gasoline Chassis
Chicago Motor Vehicle Company exhibited several gasoline vehicles at the 1900 Inter Ocean Automobile Exhibition and promoted bodies that could be interchanged on a common motor chassis, allowing passenger and commercial use. Accessible evidence does not recover formal model names, the complete body catalog, dimensions, transmission or prices. This evidence-gap family accounts for the Chicago-badged production program after president W. R. Donaldson redirected emphasis toward commercial vehicles. Worth-badged cars from the same company are cataloged separately under Worth.
Dates with their meaning intact
This record contains useful sourced evidence, but it does not yet meet the reference-ready standard. Still needed: attributed imagery. Fields we cannot source stay empty rather than guessed.
No dependable Chicago-badged output or model/body split survives.
