Agree that it's way to early to make a final judgement.
I'm sure that RC's impression is strongly influenced from the somewhat cooling off Porsche sales in Germany. Fresh data from yesterday's shareholder letter (1st halfyear of Porsche's FY - August 1 -January 31):
Germany: - 4.6%

North America: + 23.3%

RoW: + 21.8%

The data presented to the financial community does not separate Cayman S numbers from Boxster numbers (shown in one single column as "Boxster Series"), but this number jumped by 162.3 % (certainly with a fair share from Cayman S but also taking into account the base effect from weak 986 sales at the end of it's lifecycle) - 997 series was up 21.7%.
What puzzles me a little bit is that Porsche does not seperately comment on Cayman S like "very successful launch" or similar which they usually do some 2 months after the launch.
My gut feeling says the Cayman S had a good start in the US, but may have a more difficult launch in Europe. I'm living in a Porsche flooded area and did see only one single Cayman S in the wild so far (launch was end of November).
BTW the car looked really beautiful in the dawn light on the autobahn. Maybe it's just me but I always like the look of any P-car looked at from another car in motion far better compared to the typical showroom perspective standing near the cars.
Anyway, maybe I'm not the typical buyer but the only "force majeur" preventing me from getting the Cayman S instead of a Boxster S definitely was not the price tag, but my wife

not willing to give up the cab fun (weekend toy, so practicality is not part of the equation in my case) - so please don't think I wouldn't like the car.
And hey, you lucky Cayman owners (or waiters) - if we're discussing (or even speculating) sales numbers or Porsche's price policy this does not imply any offenses to you or any disrespect regarding a great car

If I would have a Cayman S on order my blood pressure would not raise if others would criticize Porsche regarding it's marketing strategy - the only thing which would raise my blood pressure is sitting in my great new Porsche for the first time and turning the ignition key
