Almost 200 Model A Fords will descend on Murray Bridge next week for a national meeting of enthusiasts.
Ninety years after the model was first mass-produced in the United States, enough are still on the road for their owners to hold a biannual catch-up that will be attended by about 420 people.
They will be based at Unity College during the week and venture out on runs to local attractions, including a mandatory run to Mount Torrens for morning tea and Mary Ann Reserve, Mannum for lunch on Thursday.
A display of more than 200 cars on the wharf at Sturt Reserve, between 10am and 2pm on Saturday, will be the culmination of the week's festivities.
Members of the public will be able to vote for a people's choice award on the day.
Organiser Gary Fischer, the chair of the Model A Ford Club of South Australia and a local, said he had always admired the vehicle.
"They've been a tough old vehicle and they keep on keeping on," he said.
"If they've got spark and they've got fuel, they'll go."
They went alright too, he said, at up to 55 miles an hour: "she'd give your Hyundai a hurry-up".
It was satisfying to have built one of his two cars from a rolling chassis, he said, though progress was not always easy.
"I tried to reverse it out of the shed and found I had the diff back to front – I had one forward gear and three reverses," he chuckled.
But the fellowship he and his wife Marg enjoyed with other owners was part of the appeal too.
"We've had a lot of fun and we've met a lot of people," he said.
"Just about all over Australia we can knock on someone's door and say 'could you pop the kettle on?'"
