The cases of Ferrari Classiche and Porsche Classic demonstrate that 'brand purity' and 'parts availability' are not mutually exclusive options. The key is to insert an intermediate layer of 'manufacturer-led paid certification': not unconditional supply, but entry barriers set by the manufacturer—if owners want to retain manufacturer certification and provenance, they must allow the manufacturer to participate in or lead the restoration process. The manufacturer gains high-margin certification and maintenance revenue while maintaining control over brand narrative definition. For brands with extremely limited production scales and prohibitively expensive tooling restart costs, the minimum approach is 'conditional parts supply while simultaneously voiding manufacturer warranty and certification.' This is already an established middle ground in the industry, avoiding the two extremes of complete embargo or unrestricted supply.
