Eightvertical louvers on the lower rear fenders directly behind the fender breakline once again characterized the widedoor Cadillac sedan. This model was also distinguished by exclusive extra-wide full-length chrome underscores and a Fleetwood insignia on the rear deck lid.
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

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.
