with similar spec and features.
No the manual doesn't cost a whole GT3 RS in expense, but true "drivers" desire so much to be involved in the driving experience that they are paying a LOT more money to have basically the same car with a manual trans vs auto (PDK). Demand is so high that Porsche has now brought back the manual on the new GT3.
Some people actually like to drive and be engaged. Count me as one of them.
I never want an autonomous car until I can't do it anymore.
