A unique 1981 BMW M1 is set to cross the auction block at the upcoming Broad Arrow Auctions event in Zürich. This specific vehicle, chassis number 4301450, is a standout for collectors, boasting a documented history of Swiss ownership from the day it left the factory, an incredibly low mileage of just 4,842 kilometers, and the distinction of being the second-to-last road-going M1 ever manufactured.
A Legacy Tied to Motorsport
The car's history is inextricably linked to Seger & Hoffmann, a firm highly respected within BMW Motorsport circles. Known for crafting bodywork for M1 Procar race vehicles and sponsoring Sauber-run entries, the company maintained a substantial collection of M1s. According to auction records, the firm's ambition was to own an example in every available color, leading them to have this particular car repainted from its original white to the red finish seen today.
Following financial difficulties at Seger & Hoffmann in 1984, the collection was acquired by Peter Bachmann. By 1986, the vehicle was brought to renowned Swiss M1 specialist Fredy Gretener to be completed. During this restoration process, the car received an engine from chassis 4301445—a common practice at the time when matching serial numbers held less significance than they do for modern collectors.
Decades of Careful Preservation
Since the mid-1980s, the M1 has seen minimal road use. It was briefly registered in 1983 and then preserved for decades under the expert care of Gretener. In 2013, the car was officially granted Swiss Veteran Vehicle status. It was subsequently sold to its current owner, with Gretener continuing to oversee its maintenance, which includes an annual test drive of approximately 50 kilometers to ensure mechanical health.
In 2023, the interior seats were refurbished using original components to address 42 years of aging, further ensuring the vehicle's pristine state.
Market Context and Value
The estimated price for the vehicle sits between CHF 450,000 and CHF 500,000. While market data from sources such as the Hagerty Price Guide indicate that top-tier, pristine M1s are currently experiencing upward price trends, the value of this specific unit remains a subject of collector debate. As noted in the auction catalog:
«The engine is not the original, and the catalog says so plainly. Against that, there's the sub-5,000 km mileage, unbroken Swiss history and the Seger & Hoffmann connection.»
The Historical Significance of the M1
The BMW M1 holds a special place in automotive history as the inaugural project of the M division. Designed to compete in Group 4 racing, it featured a sophisticated mid-engine layout, a tubular space-frame chassis by Gianpaolo Dallara, and iconic styling by Giorgetto Giugiaro. Despite being a masterclass in engineering, the vehicle faced headwinds during the late-1970s fuel crisis, leaving many of the 399 road-going examples to sit in showrooms for years before finding homes.
As this rare machine heads to auction, it presents a compelling choice for collectors: does the historical importance and near-unused condition outweigh the lack of a matching-numbers engine?
