The Cadillac Series 40-62 is a series of cars which was produced by Cadillac from 1940 through 1964. Originally designed to complement the entry level Series 61, it became the Cadillac Series 6200 in 1959, and remained that until it was renamed to Cadillac Calais for the 1965 model year. The Series 62 was also marketed as the Sixty-Two and the Series Sixty-Two. The Series 62 was used to introduce the Cadillac Coupe de Ville and the Cadillac Eldorado which started out as special appearance packages that were later placed into production.

Fifth generation (1957–1958)

For 1958, there was a new grille featuring multiple round “cleats” at the intersection of the horizontal and vertical members. The grille insert was wider and new bumper guards were positioned lower to the parking lamps. New dual headlamps were used and small chrome fins decorated the front fenders. Tailfins were less pronounced and trim attachments were revised. The word Cadillac appeared in block letters on the fins of base models. On the sides of the car were five longer horizontal wind splits ahead of the unskirted rear wheel housing and front fender horizontal mouldings with crests placed above the trailing edge and no rocker sill trim. The convertible and the De Villes used solid metal trim on the lower half of the conical projection flares, while other models had a thin ridge molding in the same location. On Series 62 Eldorados, a V-shaped ornament and model identification script were mounted to the deck lid. Series 62 Eldorados also had ten vertical chevron slashes ahead of the open rear wheel housings and crest medallions on the flank of the tailfins. Broad, sculptured beauty panels decorated the lower rear quarters on all Series 62 Eldorados and extended around the wheel opening to stretch along the body sills. Standard equipment on all Series 62s was the same as the previous year. All new was an extended deck Series 62 sedan which, along with the Series 62 Sedan deVille, stretched 8.5 inches longer than the regular 4-door Series 62, and a special order Series 62 Eldorado Seville of which only one was actually built. Excluding export sedans and chassis only, the Series 62 offered an all-time record of nine bodystyles this year. The infamous Cadillac Air-Suspension was optional. The following year De Ville and Eldorado were spun off onto their own series.
