Porsche offered a “Flachbau” (“slantnose”) 930 under the “Sonderwunschprogramm” (special order program) beginning in 1981, an otherwise normal 930 with a 935-style slantnose instead of the normal 911 front end. Each Flachbau unit was handcrafted by remodeling the front fenders. So few were built that the slantnose units often commanded a high premium over sticker, adding to the fact that they required a premium of up to 60 per cent (highly individualized cars even more) over the standard price. Several sources claim the factory built 948 units. The Flachbau units delivered in Europe usually featured the 330 hp (246 kW) performance kit.
