The Calais was the new entry level Cadillac for 1965, replacing the 62 Series, which dated all the way back to 1941 and the demise of LaSalle. The new model cut ties with the fins and chrome that Cadillac had been utilizing since the 1950s, as the Calais took on a squared shape and headlights were stacked vertically Available body styles included two- or four-door hardtops along with four-door sedans, which Cadillac hadn’t offered since 1956. Side glass was curved and a new perimeter frame moved the engine forward six inches, offering more interior room. The standard 429 cubic inch engine produced up to 340 horsepower.
For 1968 Cadillac bumped its engine size to 472 cid, producing 375 horsepower; this engine design would be used until 1976. Overall body styling changed little; though side marker lights were added, and the hood was extended by 8.5 inches to accommodate hidden wipers. Minor changes to the grille caused the rectangular parking lights to be set slightly higher. There were 14 new paint colors and 147 upholstery combinations. Power windows were now standard. The slow-selling Calais four-door sedan was dropped.
In 1969, the Calais’ front and rear was redesigned, bringing it into line with the successful Eldorado style. Headlights were realigned horizontally for the first time since 1964 and the buttressed fenders carried the turn signals, parking and cornering lights; vertical taillights wrapped around the fins. The frame was stretched by 7.5 inches and the hood by 2.5 inches.
The Calais represents an unusual niche in the luxury market as an “affordable” luxury item. Comparatively few were sold against De Villes, so they are quite rare now, though it is debatable whether the Calais was anything more than badge engineering. Pre-emission cars are superior performers and reliable, if thirsty.
