The Surrey Mini Owners' Club and Brooklands Museum will try to set a new world record for the fastest build of a classic MIni on 25 March.
The challenge for the team of 12 volunteers during Mini Day is to replicate the assembly of a Mini as it would have been done at the Longbridge factory: a complete running car has been stripped down into parts as it would have been delivered to the assembly line.
Once completed, the car will have its electrics and mechanicals safety-tested and then be run up the Test Hill to complete the challenge.
And then someone will win it! A raffle to give the car – a 1990 Mini Flame Red – a new home will cost £2 per tricket and be drawn at the end of the day.
Organisers are expecting more than 1000 minis on-site for MIni day, with a 1959 Austin Seven survivor taking pride of place by the Shell Pagoda.
Brooklands said: "As usual, classics like the Mini Cooper, Traveller and Clubman will be out in force, but the extraordinary range in variants such as the Riley Elf and Wolsey Hornet will show just how broad this model is.
"The Paddock, the period Motoring Village, Members’ Banking, Aircraft Park and all other areas of the Museum – recognised as The Birthplace of British Motorsport – will host club displays, customised vans, Mini Mokes, Scamps and the modern BMW models, which have led to a revival in interest in this evergreen little car."
Dozens of stalls will be selling memorabilia, spares and other Mini items, while nearly 40 Mini clubs have booked their places, including the Belgian and Dutch contingents of the International Mini Moke Club.
The first 1000 Minis through the gates will receive a special commemorative car sticker.
