More than 200 vehicles are expected to be on display including the original Ghostbusters car and one used in the Judge Dredd movies.
Ellesmere's Model Railway Society will be setting up displays at the event on July 10 and there will be a variety of stalls.
Councillor Tim Hunter, one of those involved in the day, said the show was free to enjoy.
"It's a wonderful way to show Ellesmere at its best," he said.
Ellesmere Carnival Committee and the Oswestry Classic Cars group will also be involved in the day.
