You obviously dit not notice that it was already the case before I added more relevant brand names to the existing attributes. It is good that thanks to my clumsiness you finally made a long overdue correction. 
However, taking example to the nearby situation of Bentley and Lamborghini, I attempted to single out two of the Stellantis brands, that you dumped, although nobody gives a damn that a company (that will probably not last long) owns the brands that people know. When they use an OSM-based tool to locate a Citroën or Peugeot shop, they will use these brand names rather than the abstract Stellantis name. Have you ever seen a Stellantis-branded car on the road ? 
It is almost as irrelevant as mentioning that d'Ieteren is the owner and operator of the nearby Audi Center Brussels, Bentley, Lamborghini, Porsche Centre Brussels, Porsche Classic and Carglass.
