The 163rd of 284 first-year Porsche 911 Turbo (Type 930) examples built for 1975, this car was originally delivered to a Japanese customer in rare Copper Brown Metallic with a bespoke tan leather interior and several factory options including a limited-slip differential and Pirelli performance tyres. After spending many years in Japan, it was acquired by the consignor and subjected to a comprehensive bare-metal restoration by marque specialists in Vancouver, encompassing a full engine and gearbox rebuild, new suspension components, and a period-correct interior retrim.
