Naseby Motoring Museum owner, Mr Amies said he was "just blown away" by the inaugural show's popularity, - it was described as the biggest event in the town since the 125th jubilee in 1996.
More than 300 cars, motorbikes and a large collection of other vintage machinery turned up.
Mr Amies then decided to put a few systems in place to ensure its future smooth-running.
A bank account has been set up, so the proceeds can be directed to charities and the main street will be closed, to allow parking for show cars, which could turn up for the 9am to 5pm event on the day.
He said people could expect more than just cars on display, listing tractors, motorcycles and stationary motors, as other attractions.
The Naseby fire brigade is providing a demonstration at 11am and the Dunedin and Invercargill police will present a dog handling display at 11.30am.
