Ford Sierra Cosworth RS500 From long-term ownership with only 15,103 miles, the rare and desirable RS500.

The original Ford Sierra RS Cosworth was the first Ford to wear the Cosworth badge and was presented to the public at the Geneva Motor Show in March 1985. It was introduced as a means of homologating the Sierra for 'Group A' Touring Car racing, with a requirement that 5,000 cars were built and sold. Launched for sale in July 1986, and based on the three-door Sierra body-shell, it was designed by Ford's Special Vehicle Engineering (SVE) and was powered by a Cosworth-designed 2.0-litre turbo engine of now-legendary repute. At this time, the Sierra Cosworth was a new kind of performance car - a 'blue-collar hero' able to humble true sports cars!

In total 5,545 cars were produced - of which 500 were sent to Aston Martin Tickford for conversion to the Sierra 'RS500 Cosworth'. If the RS Cosworth was a homologation car, the RS500 was an evolution special. Once Ford had built the requisite 5,000 RS Cosworths, 'Group A' rules allowed an upgraded 'evolution' model to be launched. This could carry changes focused on improving its racing potential, provided Ford sold 10% of the original number as road cars, hence the 500. The RS500 was announced in July 1987 and had a mechanically uprated Cosworth engine (more similar to the one to be used in competition), with power boosted to 224bhp, upgraded brakes, modified bodywork and the cachet of being hand-assembled - the RS500 really is the ultimate 1980s Fast Ford!

E389 ERC was first registered on 8th September 1987 and retains it’s original and unmodified engine and gearbox. It remains finished in the original black factory paint and has been professionally stored by our late and much respected vendor since his ownership began back in 2006 and seldom used. The history file confirms the indicated mileage of 15,103 as genuine, with several lengthy periods of the car being off the road, but regularly maintained. The tyres, which look to be original, are starting to crack and perish slightly so a new set will be required if our lucky purchaser intends to use the car, perhaps keeping the originals as part of its provenance. The car is accompanied by its Service Pack, spare keys and an MOT valid until 1-10-2022.

This is an extremely rare and highly revered model that epitomises the era, enjoys a dedicated following and has a formidable motorsport legacy - all being vital factors which won't diminish over time and, realistically, it’s value is only going one way. This lovely Cosworth is in the sort of condition that only comes with low mileage and ownership, and your early inspection is welcomed and encouraged to acquaint yourself with this very special RS500.
