RIOM, FRANCE — In October 2026, the quiet historical town of Riom, nestled in the heart of France’s Puy-de-Dôme department, will become the epicenter of a major heritage event. Outside the local Hôtel des Ventes, a striking mechanical procession is taking shape. Heavy khaki trucks with their hoods propped open, vintage agricultural tractors, and rare mechanical relics sit idling in spirit, waiting for their turn under the auctioneer’s gavel.
Passersby and seasoned collectors alike stop to admire the sheer scale of the machinery. An imposing American GMC military truck commands the tarmac, while a uniquely shaped Renault command car captures immediate curiosity. Yet, these machines are not fresh off the set of a Hollywood war movie. They are preparing to leave their long-time home, signaling a dramatic turning point for the lesser-known, deeply impressive reserve collection amassed by the late Guy Baster.
Behind this high-profile dispersion lies a strategic, bittersweet family decision: to sacrifice the heavy, voluminous assets of the collection to protect, fund, and preserve the future of the crown jewel—the renowned Baster Motorcycle Museum.
1. Main Facts: Unveiling the Hidden Reserves of Guy Baster
For decades, the name Guy Baster has been synonymous with motorcycle heritage in France. A local garage owner in Riom turned national icon of vintage motorcycling, Baster dedicated his life to preserving two-wheeled history. He established the famed Musée Baster – Musée de la Moto on Rue de l’Ambène in Riom. Spanning approximately 2,000 square meters of exhibition space, the museum houses over 400 meticulously restored motorcycles dating from 1905 to 1985. It is internationally recognized as one of the premier institutions dedicated to motorcycle history in Europe.
However, even the most devoted enthusiasts of the museum were often unaware of the breadth of Baster’s secondary passion. Beyond motorcycles, Guy Baster possessed an insatiable appetite for mechanical history of all kinds. Over the years, he quietly accumulated a massive cache of vintage military trucks, specialized tactical vehicles, military parts, and historic agricultural tractors.
Stored away from the main public exhibition spaces, this secondary collection remained largely behind the scenes. Following Baster’s passing on April 30, 2026, at the age of 74, his family inherited the monumental task of managing this sprawling, heavy-duty mechanical legacy. The upcoming auctions in October 2026 will bring these hidden reserves into the harsh light of day, offering collectors a once-in-a-lifetime opportunity to acquire pieces of rolling history.
2. Chronology of the Dispersal: Two Major Auctions in October 2026
The liquidation of the non-motorcycle reserves has been meticulously planned by the Baster family and will unfold across two distinct, highly anticipated chapters under the guidance of judicial auctioneer Master Xavier Butant. Both sales will take place physically at the Riom Hôtel des Ventes (located at 101 Rue du Moulin-d’Eau) and digitally via the live-bidding platform Interenchères.
Chapter I: The Military Fleet (Friday, October 16, 2026)
Opening the auction calendar on Friday, October 16, 2026, at 11:00 AM, the spotlight will fall entirely on military and tactical hardware. A total of 22 primary lots will cross the auction block.
The catalog reads like a wishlist for military vehicle restoration enthusiasts and historians:
- Renault Command Car R 2087 (1960): A classic, canvas-topped French military vehicle estimated between €18,000 and €22,000.
- Jeep Hotchkiss M201: Several units of this iconic French-built variant of the Willys Jeep will be offered, with estimates ranging from €15,000 to €20,000.
- GMC M1072 Truck (1942): A heavy-duty American World War II veteran, valued between €12,000 and €15,000.
- REO M35 6×6 Truck: The legendary American multi-fuel tactical truck, anticipated to fetch between €15,000 and €20,000.
- Berliet GBU 15 (1961): A heavy French all-wheel-drive military truck estimated between €10,000 and €12,000.
In addition to these headline lots, the inventory includes Saurer trucks, a classic Renault Goélette, a Polish Żuk fire truck, military trailers, seating benches, specialized engines for Renault AMX 13 armored vehicles, De Dion-Bouton mechanical parts, and even a Moto Guzzi Ercole flatbed motorcycle.
Chapter II: The Agricultural Heritage (Saturday, October 31, 2026)
Just over two weeks later, on the afternoon of Saturday, October 31, 2026, the focus will shift drastically from the battlefields of the 20th century to the rolling farmlands of rural Europe. Master Xavier Butant will oversee the dispersal of 41 lots comprising vintage agricultural tractors.
This sale is heavily anchored by rare Vendeuvre tractors—a historic French agricultural brand deeply tied to regional farming heritage—with estimates ranging modestly from €700 to €1,800 depending on the model and condition. However, the undisputed star of the agricultural catalog is an unexpected international icon: a Porsche Junior L diesel agricultural tractor dating from 1960, expected to command between €4,000 and €6,000.

4. Official Responses and Family Perspectives
The decision to auction off decades of accumulated mechanical history was not made lightly. For the Baster family, the passing of patriarch Guy Baster on April 30, 2026, marked the end of an era, forcing an immediate evaluation of how best to manage his sprawling estate.
In an exclusive interview with regional daily newspaper La Montagne, Flavien Baster—son of Guy Baster—shed light on the motivations driving the upcoming sales. Addressing the heavy logistical and financial burden of maintaining such a massive, disparate collection, Flavien explained the core rationale behind parting ways with the trucks and tractors:
"The goal is to protect the motorcycle collection," Flavien Baster stated clearly.
By dispersing the voluminous, space-consuming military vehicles and agricultural tractors, the family can streamline their operational focus. The revenue generated from the October auctions will be funneled directly into securing the long-term future, maintenance, and modernization of the Musée Baster. It is a pragmatic maneuver designed to ensure that Guy Baster’s true life’s work—his world-class motorcycle museum—remains viable, protected, and accessible to future generations of motorcycling enthusiasts.
5. Implications: Preserving a Legacy While Relinquishing the Past
The upcoming October 2026 auctions in Riom carry profound implications for both local cultural heritage and the broader European vintage collecting community.
Safeguarding the Core Museum
First and foremost, the strategy appears sound from a preservation standpoint. Museums dedicated to niche historical categories face steep financial realities in the 21st century. Rising real estate costs, maintenance demands, and insurance liabilities make running a 2,000-square-meter private museum increasingly difficult. By trimming the mechanical "fat"—the massive trucks and heavy tractors that require separate storage and extensive maintenance—the Baster family ensures that the core motorcycle collection is not compromised by financial strain.
Re-evaluating Industrial and Military Heritage
Secondly, the dispersion of these reserves injects dozens of rare historical artifacts back into active circulation. Vehicles like the Renault Command Car, the GMC M1072, and the Porsche Junior L tractor will find new homes among passionate collectors who possess the specialized skills and resources required to restore and maintain them. Rather than sitting indefinitely in closed reserves, these machines will likely reappear at heritage vehicle rallies, agricultural exhibitions, and historical reenactments across Europe.
The End of an Era in Riom
Finally, the sales mark the symbolic closing chapter of Guy Baster’s idiosyncratic approach to collecting. Baster was part of a vanishing breed of traditional, unyielding hoarders-turned-archivists who rescued machinery simply out of a deep-seated love for engineering and mechanics. While it is sad to see the hangars emptied of their khaki giants and vintage farm workhorses, the sacrifice guarantees that the Musée Baster will continue to stand proud on Rue de l’Ambène.
As Master Xavier Butant drops his hammer in October 2026, bidders will not merely be purchasing old iron and steel; they will be casting votes of confidence in the survival of a legendary French cultural institution. Whether attendees arrive with multimillion-euro acquisition budgets or simply to spectate the mechanical procession outside the Riom auction house, the event promises to be a poignant, unforgettable celebration of industrial history.
