The inexorable transformation of the car industry towards electrification is propelling the greatest hits of yesteryear to new heights, it seems: this low-mileage Ford Sierra Cosworth sold by Silverstone Auctions this weekend for nearly £600,000.

The 1987 Ford Sierra Cosworth RS500 is in time-capsule condition, with just 5192 miles on the odometer, propelling its value way past its £150,000-£180,000 estimate.

It sold at Race Retro on 25 February for £596,250, including fees, smashing the previous £135,700 record for a Cossie set by Silverstone Auctions in 2022.

A price bubble? Why prices for modern classics are sky-rocketing

There is growing realisation that modern classics are a rare breed that will not be replaced; those sceptical of the march of EVs are hankering for the more analogue greatest hits from yesteryear, pushing prices up. 

Silverstone Auctions sold this Cossie for a world record price

The Sierra Cosworth fits the bill perfectly. Introduced in 1985 as a homologation special to propel the Blue Oval to Group A touring car race success, its outrageous performance and whale-tail style quickly made the roadgoing hot hatch a hit among enthusiasts.

In many ways, it came to define the excess of the 1980s/1990s – that heady period that begat specials like the Lotus Carlton and turbocharged, all-wheel drive rally specials including the Lancia Delta Integrale and Subaru Impreza WRX.

The RS500 is peak Cosworth; it was unveiled in July 1987 with power boosted to 224bhp and extra winglets for its outrageous spoiler. Just 500 examples were hand-assembled by Aston Martin Tickford, underlining its appeal as the ultimate fast Ford.
