St Marys Community Car and Bike Show president Gerhard Risti said the annual show had been running for 13 years, and never failed to create a buzz in the small East Coast town.

"It's one of the few car shows that are still held in the centre of town," he said.

"Most car shows are on an oval, but this just creates a great atmosphere."

The car show all started with St Marys Caltex owner Grant Faulkner, Mr Risti said.

"He started it 13 years ago, and as a group together we've built the show," he said.

"We've gone bigger and bigger each year," he said.

The show did not originally take place in the streets of St Marys, but as things grew more space was needed.

"We decided to do it in the middle of town," he said.

The car show really helped St Marys' businesses during one of the quieter times of the year, he said.

"We do the car show on the June long weekend to help keep all the businesses going and to give them a great day of income," he said.

"Usually, the winter time is slow in country areas."

The show also coincided with the Bay of Fires Winter Arts Festival, which is taking place across the East Coast until June 10.

"We've combined the two, sharing a great turnout of people coming.

Mr Risti said there were about 300 cars being shown.

"Through the day there are around 800-plus people walking through," he said.

He said they had been lucky with the weather this year, as the event was largely weather dependant.

"It is weather dependant. If the weather is good, we usually have a great turnout," he said.

"On a nice day, people don't mind if it's a cold start."

Mr Risti said there was something for everyone at the show, with a market taking place in the hall, live music being performed, and food available for patrons.

Some of the highlights of this year's event included a Porsche, and collections of cars from clubs around the state.
