You should know by now that, when it comes to options on Porsche vehicles, choices abound. You should also know that costs abound, and that holds especially true for special-edition models like the new 911 S/T. It already has an eye-watering base price of $291,600, but run wild with options and you'll quickly add the equivalent of a new 718 Cayman S to the sticker. And that doesn't include $13,500 for the cool matching watch.
