You know why we are here. If there is a Porsche in a rare or interesting color, I’m taking a peek. Even better if color on the inside is just as cool as the outside. You can probably see where I’m going with today’s car, a 2012 Porsche 911 Carrera S up for sale in Ohio. This example is finished in Radium Green, a color first debuted way back on the 356. As cool as this color is, not exactly something that would appear on the option sheet for a new car. Understanding that, I figured this has to be a paint-to-sample car given it is a historical color. Surprisingly, this is the much more expensive option than having Porsche spray the car for $7,500.
