Perhaps, they could subcontract the routine work to other garages? Things like oil change, brake pads and routine inspection, for example?

Not possible, at least not in Germany. In Germany, dealerships are completely separate, you won't see a "mixed" Porsche/Audi/VW or Porsche whatever other brand dealership. Plain Porsche. There was a huge campaign to establish that years ago, the so called CI (corporate identity) implementation. In the past, many Porsche dealerships were also Audi and/or VW dealerships. No more, at least not in Germany.
