Well, as noted above the 6MT already makes my Cayman rare (in the 10%). In addition, "maxing out" on both luxury and performance options further adds to it being unique. About the only options we missed are the 20" wheels (the spouse and I could not agree and the lock date was upon us so we opted for the ones most similar to the 2014 Cayman) and the 18-way seats (she found them to be less comfortable, especially getting in and out of the car, and we were used to the 14-way seats in the 981 so we opted for those). The car is absolutely fabulous!
How unique is your 718 (as per Porsche)? ..Two per year!
