Members of the Hauraki Vintage Machinery Club can't bear to see old machinery rusting away in dirty old paddocks.
The club's 35 members are keen to restore and preserve vintage cars and machinery to keep the automotive history alive.
They're holding their popular Crank Up Weekend this Sunday and organisers are inviting anyone with a vintage or classic car, or truck to joy-ride to Kaihere Domain and join the display.
That applies to any Repco Beach Hop participants who are keen too, says club president Peter Williams. His specialty is restoring vintage international tractors.
Usually about 100 vehicles are on display on Crank Up day, he says.
