In 1989, Porsche concluded the 930 era, and to celebrate, they upgraded the transmission to a 5-speed with a hydraulically assisted clutch. 600 cabriolets were sold to buyers in the USA, and fewer than 10 were finished in the rare Stone Grey metallic color. This particular example has only 31,000 miles on the odometer and has had three owners since new. It comes with an excellent service history, a full interior tonneau cover, and a Certificate of Authenticity (C.O.A.).
