p.1 #1 · 2012 Porsche Cabriolet's on 101 South of SF
5 of them were in a line, with a 6th (yellow coupe) pulling into SFO airport international terminal. The coupe had all German license plates. They each had bony panels that looked like prototypes, and all of the rear taillights were painted on (or stickers). Only front lights were working. They were the style of the 2012 911, so my guess is test models. Pretty cool stuff!
