Harley J Earl designed a Cadillac Eldorado convertible for the 1953 Motorama which had such features as a wraparound windscreen and a notched beltline. A limited run of these Eldorada convertibles were sold in 1953. For 1954 a new GM C-body body was created for the Series 62 and its derivatives, designed by Edward Glowacke but clearly taking cues from the Harley Earl show car. Notable at the front were the chrome 'Dagmars' set into the grille as bumper extensions, and said to be inspired by a Lockheed fighter plane. A 331cu in (5,425cc) powered the Cadillac but this was unchanged from previous years. Series 62 (including the DeVille) and Eldorado models were on a 129-inch wheelbase with Fleetwood models being 149.8 inches. The Eldorado was an upmarket model, but no longer the special production car that it had been in 1953; it was also a lot cheaper and sold more. There were facelifts in 1955 and performance hikes, with new grilles and a larger engine in 1956. The Eldorado expanded in 1956 from just a convertible, to include the Eldorado Seville 2-door hardtop and the renamed Eldorado Biarritz convertible. The deVille range also expanded in 1956 with the 4-door Sedan deVille. A new body on a new X-frame chassis was introduced in 1957.
