Recognizing the importance of the iconic open-topped Speedster across the globe following the introduction of the 911 Cabriolet in 1982, plans began to take shape for a new Speedster model utilizing the “G-Series” 911 platform. Materializing in 1986 as the Speedster Studie, the modern interpretation utilized the narrow-body 911 Carrera 3.2 with a low wraparound screen and distinctive raised double-hump hard tonneau cover behind the front seats. The Pearlescent White Metallic concept dazzled audiences at the 1987 Frankfurt Motor Show, and, fittingly, was on sale in production form by 1989, just in time to celebrate 25 years of the 911 and bid farewell to the spectacular G-Series generation of 911. The one-year-only Speedster was typically based on the wider body of the 911 Turbo Cabriolet, which was revised by chief designer Tony Lapine to incorporate numerous styling features of the original 356 Speedster. It featured the Turbo's flared fenders as well as a highly raked windshield that transitioned through a low-slung Haartz fabric soft top to a raised hump-back hard tonneau cover replacing the rear seats to complete the iconic Speedster shape. The brakes, suspension, and wider Fuchs wheels were also borrowed from the 911 Turbo. Curiously, two styling elements from the 911 Turbo did not typically feature on Lapine's Speedster: the larger front spoiler and the Turbo's iconic rear wing.

For some customers, the lack of front and rear spoilers was an affront to the muscular look of the Turbo-bodied Speedster, a look perhaps better suited to the narrow-bodied version. No, for them only a 'Full Turbo Look” would do, and “Full” meant the deeper front spoiler with its full-width lower lip and the iconic rear Turbo tail. Of the 2,104 1989 911 Speedsters produced, just 69 were specially ordered with option code M491 “Full Turbo Look,” a configuration noted to be available only to the Swiss, New Zealander, and Australian markets.

One of the rare 3 percent of Speedsters so ordered, this 1989 911 Speedster M491 Full Turbo Look was originally ordered by Charlie Zeller of Wil, Switzerland, owner of Zeller Wil AG, a specialized dealer of jewelry and timepieces. In addition to the rarely seen M491 option code, Zeller specified his new Speedster in classic Grand Prix White over a Black full leather interior selecting limited slip differential (M220) and air conditioning (M559) as additional factory fitted options. According to the original Warranty and Maintenance book the car was delivered to Zeller via City Garage AG in Lerchenfeld, Switzerland on 2 August 1989. At a point, Zeller parted with the car, selling it to Robert Halter of Wetzikon and then later Bauma, Switzerland. The service book records servicing at official Swiss-based Porsche dealerships under their ownership. The car was clearly well enjoyed during the Alpine driving season throughout the 1990s by both as evidenced by the 51,818 kilometers (approximately 32,200 miles) accumulated by the end of the decade.

In 2002 this example, one of just 69 M491 Full Turbo Look Speedsters, became an early member of the consignor's world-renowned Swiss-based Porsche collection. Known best for an impressive selection of factory produced “one-offs,” this, the rarest 1989 911 Speedster variant, found an open arm welcome. Acquired with approximately 60,250 kilometers, the car would, along with the rest of the collection, make the move to the United States in 2020. Today, this rare Speedster retains its factory protection wax and features 66,735 kilometers–just 6,485 additional km since acquisition–a sure sign of the preservation and care afforded under current ownership. No doubt this rarest variant of the 911 Speedster remains a highly collectible automobile and is offered with a fresh service from Sacio Enterprises from a world-famous Porsche collection with its original tools, jack, spare, and set of books.
