This lot will be auctioned via Iconic Auctioneers, The Iconic Sale at Silverstone Festival 2025 - Collectors' Cars on Saturday the 23rd of August, The Wing, Silverstone Circuit, NN12 8TN. At its introduction in 1982, the Sierra's revolutionary new shape proved a touch more divisive than Ford had anticipated and some serious marketing became a priority, so it was the obvious choice to become the platform for Ford's new competition aspirations in conjunction with Cosworth. It fitted the brief well as it was rear-wheel drive, had good aerodynamics, albeit being prone to lift at high speeds, and was available as a three-door. The new body kit and rear spoiler would sort out the lift issues but, more importantly, Ford still needed to build 5,000 units for homologation, somewhat worrying when the company's initial approach to the dealer network came back with an estimate that suggested they could sell around 1,500 units! The eventual sales record is, of course, history. Ford went on to sell 5,545 three-door cars including the RS500, of which only 500 were built, and the Cosworth engine also found its way into nearly 30,000 Ford Sierra Saloons (Cosworth three-door, Sapphire two-wheel drive, and four-wheel drive). Finished in Ford Motorsport Diamond White with the traditional grey cloth interior, this very special, UK-supplied, right-hand drive example remains in truly remarkable, original condition. The warranted mileage is just 27,715, corroborated by older MOTs and service stamps in the dealer service record. First registered on 24th November 1986, the car was subsequently sold twice in its first four years before being purchased by its next enthusiast vendor who retained it for the next 32 years. The 32-year, long-term owner was a Ford employee at the time, who loved, cherished and maintained the car to a very high standard. Many cars represent part of the family, and as a Ford technician at the time, and remaining a Ford enthusiast, it is undeniably fantastic to see such a well-maintained example, retaining its totally original specification and kept in this way purely out of the love and respect for the car. It is an incredibly special example that has always lived in the garage, being maintained and kept as pristine as possible. He then sold the car through our NEC auction a few years ago and it has formed part of our private vendor's impressive private collection ever since. He has followed on as the last long-term vendor did and ensured the car has been kept in heated storage to ensure its originality is kept and respected. It's supplied with a good history file containing the all-important original service book, service schedule and invoices for parts over the years, as well as a selection of old MOTs. Pleasingly correct and immaculately presented, this RS Cosworth comes with all the correct documentation, an impressive history file and the kudos of its FoMoCo heritage. So seldom seen in such fabulous condition with such impressive originality, this is one of the finest Sierra Cosworths to come to market in recent times. We are privileged to have been asked to sell a number of these ever-popular performance saloons cars and feel that, given this car’s history, low-mileage and fabulous condition, this 'Cossie' is very sensibly guided and one of the best examples we have seen.
