Overview

Few model names carry as much weight as the Porsche 911. The 1975 and 2017 iterations represent different chapters in this storied nameplate's history, each reflecting the priorities and technologies of its era. The 2017 Porsche 911 GT2 RS holds a clear advantage in raw power with 700 hp compared to 300 hp, a 400-horsepower difference that shapes the driving experience. Under the hood, the contrast is notable: the Porsche 911 uses a Flat-6 SOHC Turbocharged air-cooled displacing 3,299 cc, while the Porsche 911 relies on a Flat-6 with 3,800 cc. Rarity plays a significant role here — with only 1,000 units built, the 2017 Porsche 911 GT2 RS is considerably scarcer than the Porsche 911's 21,589 examples. On the collector market, the 2017 Porsche 911 GT2 RS commands a significant premium over the 1975 Porsche 911 Turbo (930), reflecting differences in prestige and rarity. From a collectibility standpoint, the 1975 Porsche 911 Turbo (930) rates higher among enthusiasts and auction houses.
