Record breaker: This 1985 Escort RS Turbo set a new record high sale for the model, selling for more than £60k at auction
Barely run in: This Ford Escort RS Turbo Series 1 is believed to be the lowest mileage example in existence
A trio of other fast Fords also had bidders in a frenzy, highlighting how the classic car world has fallen head over heels for the marque in recent years - sending prices spiralling.
The final Sierra Sapphire Cosworth 4x4 to leave the production line, registered in 1993, sold for £35, 438 - above its top £29, 000 estimate.
Meanwhile, A 1978 Ford Capri S sold for £23, 625 and a 1970 Capri RS2600 was bought for £25, 875.
A 1996 Ford Escort Cosworth Lux with just 7, 800 miles from new was 'regretfully withdrawn from sale', despite expectations of a £38, 000 to £44, 000 sale price.
The auction raised a total of £4.4m, with the sale of some extremely rare exotica - namely a 1991 Jaguar XJ220 previously owned by the Sultan of Brunei that sold for £315, 000 and 1956 Porsche 356A T1 Cabriolet that fetched almost £197, 000.
But it was the 5, 568 mile Escort RS Turbo that grabbed the headlines, with a bidding war pushing prices to a new record high.
With just one registered owner from new, this example has lived a pampered life.
Since 1999, it's barely turned a wheel. But it's not been static in a barn or an unopened storage unit - instead it was kept in a carpeted and temperature controlled garage.
Unmolested, totally original and still in concours condition, the race-replica Escort saw plenty of fanatics turn out at the NEC to watch the bids.
Speaking after the sale, managing director of Silverstone Auctions, Nick Whale, said: 'This is a very special example of the legendary Ford Escort RS Turbo and it certainly proved popular here at the UK's biggest classic car show.
'The atmosphere when the car was under the hammer was electric and I'm delighted we've been able to secure such a great price on behalf of our vendor, as well as breaking a world record.'

Rare RS: Just 500 extra special examples of the Cosworth RS500 were produced. This one fetched £90k
Another 1980s rally hero from Ford also saw major interest.
The 1987 Ford Sierra Cosworth RS500 with just 13, 961 miles on the clock was bought for £90, 000 - the same price as a brand new Porsche 911 Carrera 4S today - and more than four times its original £19, 950 cost.
With deliveries due for the all-new Ford Focus RS, which reportedly received 500 pre-orders before the performance figures for the car was even announced, owners might now think twice about putting miles on their new all-wheel-drive hot hatchback.
Silverstone Auctions, when detailing the Cosworth RS500, said fast Fords from the 1980s and 1990s are becoming increasingly sought after. In fact, they are becoming some of the most hotly pursued classics in the current market.
While the special rally versions were rare when first sold, other more common fast Fords - that were once family and even company cars - are also selling for big bucks. A prime example was the 1993 Sierra Sapphire Cosworth - said to be the final one produced, which was bought for £35, 438.
Along with as a plethora of Aston Martins, Ferraris and Porsches, a restored Lotus Ford Cortina Mk1 sold for £50, 625 and a '66 Lotus Elan previously owned by actor Peter Sellers and a '73 Ferrari 365 once belonging to boxer Sir Henry Cooper achieved £50, 000 and £40, 000 respectively.

But it wasn't just cars that went under the hammer - some more unconventional lots helped the auction achieve the £4.4m total.
Highlights included an official Ferrari F1 team race simulator from 2006 that would have been used by Michael Schumacher that sold for £23, 500, a fully restored 1978 Evel Knievel pinball machine that achieved £9, 400 and the back end of a BMW Z3 that had been modified into a living room sofa - someone paid £1, 500 to sit back and relax in car-seat comfort.

An Evel Knievel pinball machine and BMW Z3 rear section converted into a sofa were two of the more unusual lots available at the auction
THE NEXT BIG FAST FORD AUCTION COULD SET YOU BACK £360K
The RS200 was produced in ultra-low numbers for the road to allow Ford to enter the model into Group B rally events in the 1990s. This example – chassis 169 – is thought to be one of the last to come off the production line.
Famed for its savage turbo 1.8-litre engine that plants 250bhp via a complicated four-wheel drive system, it can out-sprint most modern supercars to 62mph. Not bad for a car that has a plastic and fibreglass lightweight bodyshell built by the same people who created the Reliant Robin.
This particular example was retained in the UK until 1994 before it was shipped to the US. In total it's covered just 1, 218 miles in its lifetime.
