more distinguished-looking Biarritz arrived for 1963. The lower body “skeg” lines of 1961-62 were erased on all Cadillacs, and wide brushed-finish rocker panel moldings gave the Biarritz closer kinship with the svelte Sixty Special. The price remained stable — a nominal two dollars less than the year before — and production, though still limited, increased significantly.
I. D. NUMBERS

NOTE:
Although neither engine displacement or output changed, the 1963 Cadillac V-8 was completely redesigned.
Quieter, smoother and more efficient, the new motor was one-inch lower, four inches narrower and 1-1/4 inches shorter than the 1962 V-8.
It was also some 82 pounds lighter, due to the use of aluminum accessory drives.
Model 6367E, the Eldorado Biarritz convertible, had special styling with untrimmed body sides, full-length stainless steel underscores and a rectangular grid pattern rear decorative grille. Power vent windows, white sidewall tires and six-way power seats (in bench seat mode) were standard in Eldorados.
