Now what’s the difference between a Boxster, Cayman, and Carrera you ask? All Porsches look similar you say? It is true that all Porsche models have similar styling, but the Carrera is by far the fastest of the three and has the most available features. It’s also a 911 so it has the longest performance pedigree of the three. I especially like the brown color with the red brake calipers! This Porsche Carrera S was spotted in downtown Sioux Falls, SD.
