"The 'RS' badge is well renowned in the world of fast Ford enthusiasts. Originating from Ford’s Motorsport division in the 1960s, the RS actually stood for 'Rallye Sport', and meant that any Ford model special enough to bear its namesake had been designed specifically for rally racing.  Due to Ford’s repeated successes in rallying during this era, the RS badge very quickly became synonymous with Motorsport and Performance. The Sierra RS Cosworth was developed as a result of a partnership between Ford and race engine designers Cosworth. The purpose of the project was to create a homologated vehicle to win European Group A racing championships. The engine was to be a 16V, twin-cam based upon Ford’s existing T88 block (commonly known as the Pinto engine). The aim was to develop a turbo-charged unit that would be capable of 300bhp in race trim. Cosworth accepted the task but only on the basis that Ford agreed to purchase 15,000 units of these engines. From there, the road legal and racing engine legend the Sierra RS Cosworth was born.
This desirable, two-wheel drive, 1998 Ford Sierra Sapphire RS Cosworth has covered just 300 miles since 2009, due to being in storage.  Upon removal from storage in January 2020, over £5,500 was spent on recommissioning it. This included the turbo being rebuilt, new Bosch fuel pump, the injectors cleaned and tested, steering rack gaiters replaced, five new tyres and a new battery. It passed the MoT in March 2020. The following June, it was taken to a Ferrari specialist for servicing, which included replacing the spark plugs and the cambelts. Finished in the original Ford Mercury grey with black leather Recaro seats, this Sapphire RS Cosworth is supplied with a V5 registration document and some MoT history, including a current MoT test certificate valid until April 2023. a file containing invoices from the recommissioning in 2020, invoices from major works carried out in 2003 and old MoT certificates. Also with the car is a complete ‘new, old stock’ handbook pack. As prices of well-maintained fast Fords are increasing, this is certainly worth consideration by any long-term investor or collector.
