AKA; Porsche’s Widowmaker Sunroof Option: A sunroof was standard equipment on most US-market Porsche 930s of this era, making a factory "delete sunroof" (slick top) quite rare Rarity Factors Overwhelming Majority Had Sunroofs: In the North American market especially, an electric sunroof (option code 650) was practically a default, mandatory-checked box on dealer orders. Finding a US-spec 930 turbo hardtop without one is an uncommon occurrence. While an informal collector consensus often quotes low double-digit or around ~70 estimated survivor/produced figures for specific narrow option configurations, official factory documentation only confirms that non-sunroof G-series turbos constitute an extreme minority, highly sought after today for extra headroom and a cleaner roofline. Enthusiast Demand: Slicktop G-body 911s and 930s are actively hunted by purists and tall drivers who want the cleaner aesthetic roofline, lower center of gravity, weight savings (roughly 15 lbs off the highest point), and extra headroom. Collector Value: Because they are so scarce, non-sunroof 930s often command a notable premium among air-cooled collectors compared to their standard sunroof-equipped counterparts, though exact valuation depends heavily on verifying the under-hood option sticker.
