For 1957, Cadillac adopted a tubular X-frame, without side rails, on all models. This resulted in greater structural
rigidity and provided for lower body lines without loss of useable space. New front end styling was marked by
rubber bumper guard tips and dual, circular parking lamps set into the lower bumper section. Side trim was
revised and a dual taillight theme was used throughout the line. By utilizing different center frame sections the
wheelbases and overall lengths of specific body styles was altered. In the 62 lineup, including the Eldorado
sub-series, three different overall measurements appeared on cars with matching wheelbases. The Sedan DeVille
was bigger than "standard" models and the Eldorado Coupe Seville and Biarritz convertible were larger still.
Identifying the "standard" 62 models were

forward from the taillamps.
A crest medallion was seen on the forward angled rear fins.
Coupe DeVilles and Sedan DeVilles had special nameplates on the front fenders.
Eldorados were further distinguished by the model name above a V-shaped rear deck ornament and on the
The rear fender and deck contour was sleekly rounded and the wheel housing was trimmed with broad,
sculptured stainless steel beauty panels.
Also seen were pointed, "shark" style fins pointing towards the back of the cars.
A three-section built-in front bumper was another exclusive trait of the two luxury cars, which came with a
long list of standard accessories.

The first pair of symbols were "57" to designate the model year.
The next two symbols indicated series as follows:
"62" = Series 62 including Eldorado Specials
"60" = Series 60 Fleetwood
"70" = Series 70 Eldorado Brougham
"75" = Series 75 Fleetwood
The immediately following numbers, beginning at 00000 for each series, indicated the production sequence
in consecutive order.
Ending numbers were the same for all series since the engines were installed in mixed production
The export sedan was shipped in CKD form to foreign countries.
The symbol "X" after Body Style Number in brackets indicates power windows optional
