1953 Series 75 Cadillac history

Styling facelifts on the cars in the 75 Fleetwood line conformed to those seen on the other models. Appearance features and equipment were about the same as in previous years. Regular production models included the Imperial eight-passenger limousine with glass partition or eight-passenger sedan, both with jump seats.

I. D. NUMBERS

Serial numbers and engine numbers were again one and the same.
They appeared on the right-hand side of the crankcase above the water pump and on the right frame side bar behind the engine support.
The first two symbols were "53" for 1953.
The next two symbols indicated the series as follows:
- "62" = Series 62 (including Eldorado)
- "60" = Series Sixty Special Fleetwood
- "75" = Series 75 Fleetwood
The remaining digits represented the consecutive unit number and began with 00000 for all series.
All series had the same ending number, which would be misinterpreted if listed.
