Information about this item:

1956 CADILLAC- GENERAL: Although a facelift was the major restyling news for 1956, there were still many changes in the Series 62 lineup and especially in the Eldorado sub-series. Totally new models included a pillarless four-door called the "Sedan DeVille" and the "Eldorado Coupe Seville". The latter represented an especially luxurious hardtop coupe, which was built to the same standards as the Eldorado convertible and similarly priced.

The annual 'beauty treatment' consisted of a new grille with a finer textured insert and the repositioning of parking lights in the bumper, below the wing guards. Buyers were given a choice of a standard satin finish grille or optional gold finish, both selections decorated with Cadillac script on the left-hand side. Standard equipment on all Cadillacs was comparable to that included the previous year.

1956 SERIES 62 V-8: On the rear side fenders of Series 62 models a narrow chrome molding and nine vertical louvers were seen. The Coupe DeVille had a model nameplate and Cadillac crest on the sides of the front fenders, while the more standard cars had only the crest.
As usual, the standard four-door 62 sedan was seven inches shorter than the other cars in the same series.

1956 SERIES 62 ELDORADO V-8: On the Eldorado coupe and convertible - the latter now known as the Biarritz, an "Eldorado" in script along with with a fender crest were found on the front fender, above and behind the wheel opening. All Eldorados featured a twin-fin hood ornament. Other extras on these specialty cars were a ribbed chrome saddle molding extending from the windshield to the rear window pillar along the beltline, a distinctive rear fender design with twin round taillights halfway up the fenders, and pointed tailfins similar to the '55 car. Both cars in the Eldorado sub-series were slightly longer than the '55 convertible.

1956 SERIES 60S FLEETWOOD V-8: Cadillac's non-limousine style Fleetwood model carried the "Sixty Special" designation in script below the Cadillac crest on the sides of the front fenders. "Fleetwood" also appeared on the rear face of the deck lid. Solid chrome exhaust extension trim moldings were set ino the rear fenders.

1956 SERIES 75 FLEETWOOD V-8: Side trim on the long-wheelbase Fleetwood models was about the same as 1955, except for the addition of exhaust extension moldings on the rear fender. This trim ran along a tapering conical flare from above the wheel housing to the rear bumper. "Fleetwood" in script appeared on the deck lid, and limousine-like styling was still used. Changes in grilles and bumpers conformed to those used with other series. Both the regular Fleeetwood and Limousine models had auxiliary seats, and the Imperial sedan again featured a glass driver's partition.

INNOVATIONS: The 1956 Hydra-Matic transmission incorporated changes that increased its size and smoothed out shifting qualities. It was developed by GM at a cost of $35 million.

MODEL/ENGINE I.D. DATA: Serial numbers and engine numbers were one and the same. They appear on the right-hand of the crankcase above the water pump and on the right frame side bar behind the engine support. The first two symbols were "56" to designate 1956 model production. The next two symbols indicated the series as follows: "62", "60" or "75". The remaining digits represented the consecutive unit number and began at 00000 for each series. All series had the same last (ending) number, which should not be misinterpreted if listed as part of the numbering sequence.
