Modern Porsche knows that they can take a bog standard 911 then remove sound insulation, air-conditioning (which can be optioned back in), a few other creature comforts, stiff up the suspension and proceed to sell it for more than the normal car. They can do this because that only thickens the special sauce that makes a Carrera a driving joy. Less is more. There once was a time when Porsche didn’t know that they could charge more for cars with fewer features.
