Since speedyellow cars are the fastest, I will support your good idea with my only after-sale dealer story (previously posted "years" ago and now lost in antiquity).
My factory delivery car finally arrived at Hoehn Porsche, Carlsbad (San Diego suburb) and, after intervention by the General Mgr in the detailing department, (another story) the German plates were located and mounted. So when I later went to mount the California plates, the front adapter presented a puzzlement due to its hole sizes. They led one to think there might be screws that were Porsche part numbers. Not so. BUT the efforts of the Service Mgr and two techs, in dropping whatever they were doing and searching out some nice stainless screws that worked, were noted and appreciated.
Actually the German plate incident and the fact that I had to insist to receive the promised interest on the $10k Factory delivery refundable deposit are a minor negative but not worth a separate post.
