Opel Monza classic cars for sale

History of the Opel Monza

The Opel Monza was introduced in 1978 as the successor to the Commodore Coupé, marking Opel's ambition to enter the executive car segment with an innovative fastback coupé. Designed and assembled in Rüsselsheim, its production continued until 1986, with approximately 46,000 units built. The Monza combined technical advancements and purposeful luxury, offering power and comfort for long-distance journeys. It also appeared in the UK as the Vauxhall Royale Coupé, reinforcing Opel's pan-European strategy and the car’s international flair.

Model History

The Monza was produced in two main series: the Monza A1 (1978–1982), identified by classic chrome trims and more understated technology, and the Monza A2 (1982–1986), which brought updates like colour-keyed bumpers and interior upgrades. Key variants include the Monza 3.0 E and the highly specified Monza 3.0 GSE. The A2 series dominates current supply and demand, accounting for over three-quarters of Monza listings and a remarkable 87% of listing views, signalling enduring enthusiasm for later models. Its direct predecessor was the Opel Commodore, while after 1986, Opel shifted focus to the Senator, thus closing its chapter of coupé flagships.

Highlights and Unique Features

The Monza’s technical and comfort features emphatically placed it ahead of many period rivals. Standout equipment in the Monza 3.0 GSE included the digital 'Mäusekino' cockpit display, Recaro sports seats, a factory-fitted on-board computer, limited-slip differential (GSE), and power accessories such as electric windows and mirrors. The sleek fastback, with its distinctive wedge-shaped nose and wraparound rear glass, highlighted Opel's modern design ambitions of the era. Particularly notable was the Monza’s balance of performance and cabin luxury, which made it a top choice for long-distance travel.

Technical Data

Special Editions and Collectible Models

The Monza 3.0 GSE stands out as the most sought-after version, featuring digital instrumentation, onboard computer, Recaro sport seats, and limited-slip differential as standard. Unique paint finishes and wheels further distinguish some of these models, and a handful of special-option models with exclusive interior finishes or limited colour schemes are prized among enthusiasts.

Weak Spots and Common Issues

Corrosion is the main concern with the Monza, especially at the front strut towers—where the design is prone to weakness and rust, risking breakage. Common rust areas also include sills, arch tips, door bottoms, rear valances, and headlight corners. Gas struts for the tailgate often fail, and dashboards are frequently cracked from sun exposure—a problem made worse by the scarcity of replacement parts. While most mechanical parts are reliable and benefit from Opel's modular approach, original bodywork and interior pieces are now rare and expensive. Engines, particularly the CIH types, are considered robust if well maintained, but buyers should be wary of poorly modified or tuned examples. The 2.5 E engine is less favoured due to thirst and lacklustre performance compared with the 3.0 E, and the five-speed manual is seen as a more desirable alternative to the automatic transmission.

Engine, Performance, Transmission and Handling

The Monza was engineered with a focus on long-distance capability, combining effortless cruising with a blend of comfort and stability. With the 3.0-litre injection engine, the Monza could achieve over 200 km/h—remarkable by late 1970s and 1980s standards. Its rear-wheel drive, standard power steering, and plush yet supportive seating made for relaxed motorway driving. The GSE, with its limited-slip differential and tuned suspension, delivered improved cornering and more dynamic handling, while the configuration of the interior—with fold-down rear seats and a spacious boot—underlined its practicality for everyday use as well as for extended trips. - Opel Monza 3.0 E (A2): 180 PS, five-speed manual, digital instruments (in GSE), known for balanced performance and durability.

Interior, Comfort, Exterior and Design

The Monza’s unmistakable fastback profile, designed as an executive coupé, set it apart from saloon peers. A signature wedge front, flush glazing, and a glass hatchback rear gave it a progressive look. The interior was spacious—unusual for a coupé—offering supportive seats (especially the GSE’s Recaros), high-quality materials, and extensive features such as power windows and climate options. Accessories such as aluminium wheels, rear pop-out windows, central locking, and green tinted glazing added a touch of 1980s luxury. Especially notable is the vivid digital dash in the GSE, one of the first of its kind. Special order paint and upholstery schemes were available, though rare today.

Other

Some Monza models were equipped from the factory with period tuning upgrades, including spoilers, side skirts, sports suspension and steering wheels. The car’s modular design, shared with the Senator, has helped preserve maintenance options. Documentation, H-registration (historic plates), and preserved user manuals are typically sought-after by buyers to demonstrate authenticity and provenance.

Summary

The Opel Monza remains a flagship of German executive coupé tradition—remarkable for its from-the-factory innovation, technical robustness, and rare-for-the-class comfort. With strong presence especially for later A2 and GSE models, today’s Monza is a compelling option for enthusiasts seeking a tangible piece of premium 1980s design and technology, backed by a solid reputation and challenging rust-prone survivors.
