Classic Ford Sierra RS Cosworth kept by same owner for past 36 years is up for auction and set to go for a FORTUNE

A CLASSIC Ford Sierra RS Cosworth kept by the same owner for the past 36 years is now up for auction - and set to go for a fortune.

This 1987 Ford Sierra RS Cosworth, with 74,990 miles on the clock, is going under the hammer with a guide price of £58,000 to £68,000.

Silverstone Auctions, who are handling the sale, claims that this black painted example is in "superb" condition.

The 1987 Ford Sierra RS Cosworth model was first registered on 26th March 1987, but it was the next day that the long ownership began when it was registered to the second and current keeper.

Silverstone Auctions explained: "A new era of performance car was launched at the RS Cosworth’s unveiling in July 1986, one of very few genuinely identifiable racing icons, approachable and unpretentious.

"Based on the three-door Sierra bodyshell, it was designed by Ford's Special Vehicle Engineering (SVE) and was powered by a Cosworth-designed 2-litre turbo engine of now-legendary repute.

"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."

This particular RS Cosworth has recently been serviced - and was correctly stored while off the road during the 2000s.

However, the car's MOT history shows incremental increases in mileage from 2014.

The sporty '80s car comes with the original manuals and service book in the original blue plastic folder, alongside historic receipts, a copy period logbook, current V5C confirming the long-term ownership and an MOT valid until April 2024.

Bidders have a little bit of time to think about their best price as the Silverstone Auctions event takes place on May 20.

This comes after a Ford Sierra RS Cosworth kept by the same owner for the past 33 years went up for auction and set to fetch an eye-watering price.

Plus, a classic Mini tucked away in a dusty garage for 33 years has been sold for an eye-watering amount at auction.
