FWIW, I have an immaculately maintained 2015 loaded Cayman GTS with the 3.4L flat 6 that will be for sale when I get my 718 SpyderI completely agree.
For the possible turbo 4-less 718 Cayman GTS, turbo 4-less 718 GT4 and, especially so for Taycan Turbo S, the solution is simple. Act with extreme prejudice and debadge the poor thing.
Any "engineering/technical" company which built their success on engineering without peers that succumbs to marketing will not last very long. I do not need Wharton degree to say that. It is like an axiom - a self-evident truth.
Finally, back to topic (kinda-sorta) ... If Porsche wants to push me to the limits of insanely irresponsible fiscal behavior, they will release NA flat 6 Cayman GTS. The only problem is that I still am very much in love with my current car. So, Porsche, it better be REALLY good.
