Details Specification

In late 1973, in contrast to most car manufacturers who were struggling with the fallout from the oil crisis, Porsche was on a high.  Having accrued a wealth of experience of turbocharging air-cooled engines from their racing programme, it seemed to make perfect sense for Porsche to utilise that knowledge by applying it to their famous rear-engined sports car, and consequently, at the 1973 Paris motor show, they unveiled a prototype turbocharged 911, the Type 930. By attaching a KKK turbocharger to its 3.0 air-cooled flat-six engine (that could trace its origins back to the 911 RSR), the 930 was the most powerful production Porsche thus far and, suddenly, the 911 was a supercar. The production-ready 911 Turbo was shown at the Paris show in autumn 1974, and not surprisingly in an era when turbocharging was seen as rather exotic, captivated the world's motoring press. Rightly, it was billed as a supremely fast and luxurious flagship model, combining ballistic performance and head-turning looks with air conditioning, electric windows and other creature comforts. The car's power and performance were celebrated (and kept on the ground) by an enormous ‘whale-tail' spoiler and a wider track that needed those bulging wheel arches to keep it decent.  Anyone who followed the ‘World Championship of Makes’ (essentially an international championship for long-distance Sports Car racing), will remember their surprise at the shape of the new 935 when it first appeared at Mugello in March 1976. Subsequently, these ‘Flat Nose’ 935s and 936s (in Group 6) were to prove very competitive in the hands of Ickx, Mass and Stommelen and during the next two seasons managed four victories in eight World Championship races and a triumph at Le Mans in each year.  However, Porsche began to worry that all these high-profile victories by the works Flat Nose cars – most famously the ‘Moby Dick’ 935 - might alienate the vast number of private clients who were investing their own money in conventionally shaped competition 911s, hence decided to restrict their efforts for 1978 to an entry at Le Mans.   However, the distinctive look of the Flat Nose or ‘Flachbau’ (literally translated as Low Build) struck a chord in the minds of their road car customers. This demand was initially catered for by ‘Kremer Racing’ who offered a conversion but subsequently this service was taken up by the factory's own Customer Department to special order (Sunderwunschen) from 1981, becoming an official option only in 1986. The front wings were steel, incorporating cooling vents and pop-up headlamps while the rears had extra cooling intakes. There were different sills and along with the body modifications came an even more luxurious interior. The car presented here simply cannot be understated.  It's extremely special and exceptionally rare.  Produced in 1989, it is therefore, an officially optioned, last-of-the-line 930 SE Flat Nose with the more desirable 5-speed G50 gearbox.  The factory SE also benefitted from a dual-exit exhaust system, limited slip differential and heated front seats.  Rare enough you’d think - but when you consider it is a UK-supplied (C16), right-hand drive, Flat Nose (506) in cabriolet form - it becomes one of the scarcest and most desirable Porsche models ever.  There were less than 10 examples of this specific model produced worldwide, with even fewer still in existence today.  This really is the 'Holy Grail' when considering a 930 model.   Furthermore, this particular car was bought new in 1989 by our vendor and has been owned by him ever since (the registered keeper was temporally recorded as his son in 1993).  As with all such small production runs of complex flag-ship models, the 930 Flat Nose was almost prohibitively expensive to buy in the late 1980s, with this car costing over £130,000 in 1989! After our vendor placed an order for it, ensuring it was highly spec’d and would wear the appropriate registration number ‘G911 WBY’, he had to wait two years for its delivery.  He collected the car from ‘Chariots of St Albans Ltd.’ (now Porsche Centre Hatfield) as part of an exclusive gathering of select customers who were able to drive away in their new 1989-registered cars at midnight on the 1st August 1989.  There is a corresponding photograph, amongst others, of this occasion in the car’s history file.  During his 28 years of ownership, the car has been serviced exclusively with the supplying Porsche Centre, always ensuring it is in sound mechanical and cosmetic order.  The car has now covered just over 35,000 miles and is in an extremely genuine condition (the speedometer failed in 2013/14 and was repaired and zeroed by Porsche.  An MoT on 04.09.13 shows 34,998 miles and the next one on the 05.09.14 shows 35 miles, followed by 18.09.15 - 92 miles, 05.09.16 - 147 miles, and today 162 miles.    We believe this is just one of two RHD, 930 Flat Nose Cabriolet ordered in Minerva Blue and may even be unique.  A striking factory colour, it suits the car’s flamboyant styling perfectly, especially when teamed with the Cream leather seats piped in Blue, deep blue carpets and gold embellishments.  The originally spec’d White canvas roof, which was prone to marking, was replaced with a correct factory item now in Navy Blue.  This car’s VIN/chassis plate, factory stickers and corresponding paperwork are all still present and wholly correct for this particular model and specification.  The accompanying history file also contains many old MOT Certificates, numerous invoices for servicing/maintenance, and an original Porsche book pack, including a stamped-up service schedule.   This is a rare opportunity to purchase not only the ultimate 911 cabriolet, but an example that has been diligently cared for within long-term single ownership.  This extraordinary car, coming to the market for the first time in almost 30 years, is not to be missed and Silverstone Auctions welcomes any inspection.
