More than 2 , 000 Birmingham-built cars will descend on their home city this weekend for the 100th anniversary of both the Austin motor manufacturer and its famous Longbridge home.
The Centenary Rally has taken the Austin Federation - formed to unite all Austin clubs and organise this event - four years to put together.
Celebrities including legendary racing driver Sir Stirling Moss and CBI director Sir Digby Jones, who was born above Longbridge Post Office, will attend the event.
It was also to have included the participation of John Towers and other members of the MG Rover management team.
This has been prevented by April's ignominious collapse of the company and the end of production at the plant.
Austin Federation chairman Tony Osbourne, a 33-year-veteran of the factory, said: "Longbridge products have been central to British motoring history since its inception and revolutionised the streets of Britain twice - with the Austin 7 in 1922 and the original Mini in 1959.
"It is the only British car factory to have produced cars for a century and whatever happens in the future its place in the motoring hall of fame is secured.
"This event is about celebrating the achievements of Longbridge over the last century.
"We have over 2,000 historic Longbridge-built vehicles booked to be at the rally, plus a fun fair, arena displays and many other attractions.
"It should be a fitting tribute to the workforce past and present, and to the vision of Herbert Austin, who founded the plant in 1905."
The Longbridge Centenary Rally will take place in Cofton Park tomorrow and Sunday.
Entrance is between 10am and 5pm on both days and costs £6 for adults with accompanied children under 14 free.
On Saturday morning Victoria Square in Birmingham city centre will be closed for a parade of 100 Longbridgebuilt vehicles on their way to Cofton Park.
This event will be flagged off by Sir Stirling Moss at 9.30am and is free.
