Fleetwood Cadillac History 1983

Fleetwood Cadillac Moels & History 1983

Luxurious as ever, limousines saw no evident change this year. Sole powerplant was again the V8-6-4 variable-displacement engine, offered only in limousines. Fleetwood remained the only domestic mass-produced limousine, though production was modest at only a thousand units. Seven or eight passengers rode in comfort and style, enjoying plentiful chrome and such extras as opera lamps.
