These dimensions place it squarely within the mid-size category of its era, offering a balanced footprint ideal for both urban and highway driving. The width variation typically reflects differences in equipment or minor model year revisions.
The curb weight of the Opel Commodore C ranges from 1200 kg to 1260 kg (2646 to 2778 lbs). The maximum allowable weight, which includes passengers and cargo, falls between 1740 kg and 1765 kg (3836 to 3890 lbs). This relatively moderate weight for a mid-size sedan of its time contributed to nimble handling and efficient fuel consumption, enhancing overall driving dynamics.
The Opel Commodore C offers a luggage capacity of between 480 and 630 liters (approximately 16.9 to 22.3 cubic feet) with the rear seats upright. By folding down the rear seats, the capacity extends to a maximum of 630 liters (22.3 cubic feet), providing additional space for larger items. This flexible cargo setup made the Commodore C practical for families and those requiring occasional increased cargo room.
The Opel Commodore C has a ride height or ground clearance of 140 mm (5.5 inches). This moderate clearance is typical for sedans of the late 1970s and early 1980s, balancing aerodynamics with sufficient clearance to navigate everyday road conditions, speed bumps, and light obstacles without scraping the underside.

Most residential garages measure around 2400 mm to 2700 mm (94.5 to 106 inches) in width and about 4800 mm (189 inches) in length, allowing sufficient clearance around the vehicle for easy access and parking, although the driver should consider the inward opening of garage doors and any storage objects that may reduce effective space.
Compared to the predecessor Commodore B, the Commodore C is slightly larger, offering improved interior space and a more modern design reflective of late 1970s automotive trends. The length increase to 4705 mm (185.2 inches) provided more legroom and luggage space. The Commodore C also featured updated styling and engineering enhancements that contributed to better ride quality and efficiency. This generation focused on refining comfort and practicality over drastic size shifts, creating a more competitive mid-size sedan within Opel's lineup.

With a length close to 4705 mm (185.2 inches), it is slightly larger than many compact cars but comparable to European executive sedans of that time. Width and height are also standard for its class, enabling it to offer competitive interior space and comfort while maintaining manageable exterior proportions for European roads.

The car featured a spacious interior, versatile luggage capacity, and handling characteristics aimed at combining comfort and driver engagement. Its sedan body style emphasized a formal yet practical design philosophy popular during the era.
The Opel Commodore C is designed with tire sizes 175/88 R14 and 175/80 R14, paired with 6J x 14 rims. These tires provide a balanced combination of grip, ride comfort, and fuel efficiency.
