The Opel Monza A1, produced from 1978 to 1986, is a coupe known for its sleek and elongated design. It measures 4692 mm (approximately 184.7 inches) in length, 1734 mm (about 68.3 inches) in width, and stands at a height of 1380 mm (around 54.3 inches). These dimensions reflect the car's sporty and aerodynamic profile, typical of coupes from the late 1970s and 1980s, offering a spacious cabin relative to its class and a low, aggressive stance on the road.

The Opel Monza A1's curb weight, which refers to the weight of the vehicle without passengers or cargo but with standard equipment and a full tank of fuel, ranges between 1370 to 1375 kilograms (approximately 3020 to 3032 pounds). Its maximum permissible weight, often called Gross Vehicle Weight Rating (GVWR), is 1900 kg (around 4189 lbs). The difference allows for passengers, luggage, and additional load while ensuring safe operation within the car's design limits.

The Opel Monza A1 provides a practical luggage capacity for a coupe of its time. With the rear seats in their upright position, the luggage compartment offers 425 liters (about 15 cubic feet) of space, which can accommodate standard suitcases and daily items comfortably. When the rear seats are folded down, the available luggage space increases substantially to 765 liters (approx. 27 cubic feet), allowing for the transport of larger or bulkier items, making it versatile for longer trips or when extra cargo space is needed.

The Opel Monza A1 typically comes equipped with 14-inch rims. The tires size designed to fit these rims is 195/70 R14. This specification means the tire width is 195 mm, the aspect ratio (height to width) is 70%, and the tires are radial with a 14-inch inner diameter. These sizes contribute to balanced handling and ride comfort, with a focus on stability and traction suitable for a sporty coupe of this era.

The Opel Monza A1 has a ground clearance of 140 mm (about 5.5 inches), which is relatively low, consistent with its sporty coupe design. This low ride height greatly enhances stability and handling, especially during cornering and high-speed driving, by lowering the center of gravity. However, it also means the car is less suited for rough or uneven terrain, as underbody scraping could occur if driven over high obstacles or uneven surfaces.

With a length of 4692 mm (184.7 inches or approximately 15.4 feet), width of 1734 mm (68.3 inches or about 5.7 feet), and height of 1380 mm (54.3 inches or roughly 4.5 feet), the Opel Monza A1 typically fits comfortably into a standard single-car garage. Most single-car garages offer dimensions around 6 meters (20 feet) in length and 3 meters (10 feet) in width, providing enough room not only to accommodate the vehicle but also allow for opening doors and some movement around the car.

The Opel Monza A1 did not have a direct predecessor of the same model name since it was introduced as a new vehicle line in 1978, positioned as a luxury coupe based on the Opel Senator. However, when compared to the Opel Senator from the same era, on which it is based, the Monza A1 maintains similar length and width dimensions but features a sleeker coupe profile and lower height. Essentially, the Monza is a sportier and more stylish alternative to the sedan-like Senator, utilizing its platform but aimed at customers seeking a distinctive, sporty coupe rather than a four-door executive car.

In terms of size, the Opel Monza A1 was competitive with other luxury coupes of the late 1970s and early 1980s, such as the Ford Capri Mk3 and Mercedes-Benz SEC models. At 4692 mm long and 1734 mm wide, the Monza was relatively long and wide for a coupe, offering more interior space compared to sportier, smaller coupes. Its design emphasized sleek lines and aerodynamic style, making it stand out for its combination of sportiness and luxury. Compared to rivals, the Monza was slightly larger and heavier, which contributed to a more comfortable ride but potentially less nimble handling. Overall, it carved out a niche as a grand touring coupe with European styling, reliability, and practical luggage space.

The Opel Monza A1 is classified as a coupe, which means it has a two-door body style designed with a sportier and more elegant profile than sedans or hatchbacks. Its coupe configuration emphasizes performance, style, and a driver-focused experience, typically featuring a sloping roofline and a more compact rear passenger space. Built between 1978 and 1986, it aimed to appeal to buyers looking for a blend of luxury, sportiness, and practicality in a stylish package.

The Opel Monza A1 has a reported curb weight range between 1370 kg (3020 lbs) and 1375 kg (3032 lbs). This slight weight variation can be attributed to different equipment levels, optional features, and slight differences in trim and mechanical components across the production period from 1978 to 1986. Variations such as engine choices, interior fittings, and added amenities may influence the vehicle's weight within this narrow range without significantly impacting performance or handling.
