What do you expect? How many 911s does Porsche even sell globally each year? 30K? There are like 700 Porsche dealers globally, so you wouldn't expect to see more than 4 cars per average each month at a dealer. Factor in high selling dealers in LA or NY or Shanghai vs middle of Germany, and the average is less. Factor in winter, and it drops further.

I'd say 1 or 2 911s is all you will ever see at many dealers at any given time.
