GROUPE LEON

What GROUPE LEON does

GROUPE LEON, legally SOCIETE DE DISTRIBUTION AUTOMOBILE MAYENNAISE (SODIAM), is a private French automotive dealership group founded in 1991 and headquartered at 250 Rue de Rennes, Mayenne. The company operates as an authorized Citroën franchise under the commercial names "Concession Citroën Mayenne" and "Châteaubriant Automobiles," running four showroom and service locations across the Bretagne and Pays de la Loire regions (Mayenne, Fougères, Châteaubriant, and Bain de Bretagne). It also trades under a unified banner across locations — "CITROEN FOUGERES - MAYENNE - CHATEAUBRIANT - BAIN de BRETAGNE" — indicating a regional multi-rooftop operating model.

The dealership's product portfolio spans the full Citroën new vehicle range (passenger and commercial, including electric ë variants from AMI through to the Holidays campervan), a multi-brand used vehicle inventory of 400+ units across thirteen brands, and a complete after-sales offering: maintenance, diagnostics, bodywork and painting, complimentary pre-technical inspection, 24/7 roadside assistance, and short- and long-term vehicle rental. Underlying commercial tools include a Citroën dealer website with online appointment booking (Citroën Rendez-Vous en Ligne), digital showroom browsing, vehicle configuration, and active Facebook/Instagram accounts.

Revenue is generated through five primary streams: new vehicle sales (one-time), used vehicle sales (one-time, multi-brand), after-sales services (maintenance, bodywork, repairs), financing and leasing (monthly subscription from €63/month on used vehicles), and roadside assistance. Customer segments are retail individuals, professionals and small businesses (utility vehicles), and families/groups (spacious and campervan models). The director of publications is M. FIXOT Anthony. No external investment, parent company, or M&A activity is disclosed in the available data.
