Thisline reflected Series 62 styling revisions, but incorporated a DeVille signature script above the lower beltline molding, near the rear of the body. Standard features on DeVilles (and on base 6200 convertibles) were the same as on closed body 6200 models, plus two-way power seats and power windows.
I. D. NUMBERS
Motor serial numbers took the same form used in 1962
the first pair of symbols changed to “63” to indicate 1963 model year
the next symbol was a letter to indicate the model as listed below
the next six numbers indicated the consecutive unit number beginning with 000001
The serial number was located at the front of the lefthand frame side bar
Motor serial numbers again matched and were found on the center lefthand side of the block above the oil pan
The alphabetical body identification code “C” was no longer used, since the short-deck Town Sedan was dropped from the 62 Series
However, the short-deck 6300 model, called the Sedan DeVille Park Avenue, was retained and used the same “D” body identification symbol
Rooflines on two-door hardtops were restyled, which brought a change in body style coding, but not in the alphabetical suffix

Although neither engine displacement or output changed, the 1963 Cadillac V-8 was completely redesigned.
Quieter, smoother and more efficient, the new motor was 25mm lower, 100mm narrower and 32mm shorter than the 1962 V-8.
It was also some 37 kg lighter, due to the use of aluminum accessory drives.
