The Ford Sierra RS Cosworth perfectly embodies the heady era of 1980s turbocharged power, and the limited-edition RS500 model has become the most coveted of all. This particular RS500 is being offered from the long-term ownership of an enthusiast who bought it in May 1996. It is build number ‘039-500’ and was first registered on 26 October 1987. A 2023 letter from Ford Motor Company states that the original intention was for the car to be finished in Moonstone, but because ‘the shells were already painted black’, it was delivered in that colour instead, and has remained so ever since. Service records show that the RS500 had covered just over 25,000 miles by 1999, and since then it has been used only sparingly. In 2023, the car emerged from eight years in dry storage and was treated to an extensive recommissioning process by Ford RS specialist Tremona Garage. The work included removing and cleaning out the fuel tank, replacing fuel lines, flushing the cooling and braking systems, and renewing all drive belts – including the cambelt and tensioner. The driver’s seat was given a new diaphragm, a new battery was fitted – complete with period decals – the offside-rear wheelarch liner was replaced, and new tyres were fitted all round. It comes with its original RS500 wheels, which have been refurbished, plus a set of OZ alloys. This superbly presented car has still covered only 27,000 miles and is being offered for sale not only with a full set of handbooks and a stamped service book, but also a raft of invoices going back to the mid-1990s. Even at a distance of almost 40 years, the Ford Sierra RS500 Cosworth remains instantly recognisable, and it’s little wonder that it’s attracted such a strong following in recent years. This is a rare opportunity to acquire an extremely collectable, highly original, low-mileage example of this performance icon.
