An opera window is a small fixed window usually behind the rear side window of an automobile. [1] They are typically mounted in the C-pillar of some cars. [2] The design feature was popular during the 1970s and early 1980s and adopted by domestic U.S. manufacturers, most often with a vinyl roof. [2]
The origin was from "opera" vehicles of around 1915 with occasional collapsible seating for extra passengers. [3] The opera window was also a feature on "formal roof" and limousine models with higher than a normal roof to accommodate passengers with top hats. [3]
The design element of a distinct, fixed, centered opera window was borrowed from such windows in horse-drawn carriages and used during the classical era of automobile styling. For example, "the Elcar in 1924 was good looking ... and even a fabric top in the style of a brougham with oval opera windows framed by landau bars". [4] Opera windows saw their demise in the 1930s.
Perhaps the most notable return was the "porthole" in the 1956–1957 Ford Thunderbird. It was provided as an option to improve rear-quarter visibility with the removable hardtop in place. "The hottest thing going was the 'porthole' window in the rear side pillar – called 'opera windows' – that came in during the horse and buggy [era]". [5]
Opera windows began reappearing in the early 1970s in such vehicles as the 1972 Continental Mark IV. Almost all personal luxury cars would adopt opera windows, usually framed by a vinyl roof. [6] Most often, opera window variants were applied on two-door hardtop or coupé models, spanning all types of vehicles from economy compacts to flagship personal luxury cars, in which latter exploding realm they became "recognition elements" seeking to add a vintage element to their styling. [7] General Motors introduced an all-new line of mid-sized "Colonade" models for the 1973 model year. Standard on all the coupes was a fixed triangular rear quarter window while higher trim versions used a rectangular vertical opera window. [8]
In some cars, an additional feature was the so-called opera light that was mounted on the outside of the B-pillar or C-pillar and illuminated when the exterior lights were switched on.
The windows were intended to offset the significant blind spots created by wide C-pillars that were characteristic of many American cars produced at this time. [9] In an age of decreasing dimensions and increasingly common use of non-opening rear side windows on 2-door models, a variety of shapes of rear windows may have helped passengers there to feel somewhat less claustrophobic.[ citation needed ]
These windows were usually non-functional; however, in the case of the AMC Matador coupe NASCAR racers, the standard roll-down quarter windows were causing aerodynamic drag. [10] [11] Penske racing requested AMC a small "porthole" to smooth the airflow when open to the wind under racing conditions. [12] To qualify as a stock item for use on the tracks, NASCAR required 500 units must be available to the public. [11] The small opera window was first an optional "D/L Formal Window Package" on the Brougham models and then a standard feature on the Barcelona II trim package. [11] [13] [14]
A hatchback is a car body configuration with a rear door that swings upward to provide access to the main interior of the car as a cargo area rather than just to a separated trunk. Hatchbacks may feature fold-down second-row seating, where the interior can be reconfigured to prioritize passenger or cargo volume.
A muscle car is an American-made two-door sports coupe with a powerful engine, generally designed for high-performance driving.
Personal luxury car is a North American car classification describing somewhat sporty, sophisticated mass-market coupés that emphasized comfort over performance.

A woodie is a wood-bodied automobile, that became a popular type of station wagon the bodywork of which is constructed of wood or is styled to resemble wood elements. The appearance of polished wood gave a resemblance to fine wooden furniture and on many occasions the wood theme continued to the dashboard and inner door panels including the rear tailgate.
In the automotive industry, rebadging is a form of market segmentation used by automobile manufacturers around the world. To allow for product differentiation without designing or engineering a new model or brand, a manufacturer creates a distinct automobile by applying a new "badge" or trademark to an existing product line.
The Chevrolet Monza is a subcompact automobile produced by Chevrolet for the 1975 through 1980 model years. The Monza is based on the Chevrolet Vega, sharing its wheelbase, width, and standard inline-four engine. The car was designed to accommodate the GM-Wankel rotary engine, but due to mediocre fuel economy and emissions-compliance issues the engine was cancelled, and a V8 engine option was substituted. The Monza name has also been used for several other cars.
A hardtop is a rigid form of automobile roof, typically metal, and integral to the vehicle's design, strength, and style. The term typically applies to a pillarless hardtop, a car body style without a B-pillar. The term "pillared hardtop" was used in the 1970s to refer to cars that had a B-pillar but had frameless door glass like a pillarless hardtop.
The Dodge Monaco is an automobile that was marketed by the Dodge division of Chrysler Corporation. Introduced as the flagship of the Dodge product line, the Monaco was introduced for the 1965 model year to replace the Custom 880, then later joined as a sub-model of the Dodge Polara.

The B platform is a full-size, rear-wheel drive, body-on-frame car platform, that was produced by General Motors (GM) from 1926 to 1996. Originally made for Oldsmobile and Buick, all of General Motors's five main passenger car makes would use it at some point. It was closely related to the original rear-wheel drive C and D platforms, and was used for convertibles, hardtops, coupes, sedans, and station wagons. With approximately 12,960,000 units built, divided across four marques, the 1965–1970 B platform is the fourth best selling automobile platform in history after the Volkswagen Beetle, Ford Model T, and the Fiat 124.
The Oldsmobile Custom Cruiser is an automobile that was manufactured and marketed by Oldsmobile from 1971 until 1992. Marking the return of Oldsmobile to the full-size station wagon segment, the Custom Cruiser was initially slotted above the intermediate Oldsmobile Vista Cruiser, ultimately above the later mid-size Oldsmobile Cutlass Cruiser.

The GM A platform was a rear wheel drive automobile platform designation used by General Motors from 1925 until 1959, and again from 1964 to 1981. In 1982, GM introduced a new front wheel drive A platform, and existing intermediate rear wheel drive products were redesignated as G-bodies.
In the context of the automobile industry, downsizing is a practice used to transition vehicles from one size segment to another. Commenced during the Malaise era, downsizing is done in response to consumer and government demands influencing vehicle design. As vehicle product lines completed their model cycles, automobile manufacturers developed the next generation of a vehicle with a smaller exterior footprint to allow for weight reduction and increased fuel economy, using a shortened wheelbase and body length.
A brougham was originally a car body style where the driver sat outside and passengers seated within an enclosed cabin, — deriving the configuration from the earlier brougham horse-drawn carriage. Similar in style to the later town car, the brougham style was used on chauffeur-driven petrol and electric cars.
