The 23rd Wheels with Attitude is set to roll in to the Dannevirke A&P Showgrounds on Sunday, January 26.
Last year the show was bigger than ever with around 560 cars, trucks, motorcycles and caravans filling the oval.
The show is hosted by the Dannevirke Wheels Club which predicts there will be between 500 and 600 vehicles on show this year.
Club president Michelle Thompson says in the past vehicle owners from as far away as Auckland, Wellington and New Plymouth have travelled to Dannevirke for the event.
Dannevirke car enthusiast Ken Mills, who has had a long association with Wheels with Attitude, says the organisers are never sure how many exhibitors will come.
