It's based on a simple format; vehicle owners bring their pride-and-joy along to the Mudgee Railway Station; park it; wander and check out what everyone else brought along; grab a coffee or something to eat; and, most importantly, talk motoring.
The Cudgegong Valley Pioneer Vehicle Club hosts the event, but vehicles of any vintage are welcome. And club vice-president David Maurice is pleased to see the uptake - and variety - because it's about fostering "motoring interest".
"It's been successful, our biggest was in November when we had about 60 vehicles - we usually get around 50 - and we got more than we expected even on our first weekend in June," he said.
"After that we decided to do it on the third Sunday of each month.
"There's no profit for the club, it's about motoring interest, which is why we encourage new vehicles too.
"And it's been bringing people to town - we've had people coming from Dubbo, Bathurst, and Orange. Because it's perfect if you've got a car on heritage registration and you can drive it a certain amount of kilometres.
"So it's also been successful for Mudgee as a whole, because while they're here they get petrol, check out the shops, and go to lunch."
To add further interest to attendees, each month a different local emergency service organisation comes along with their vehicles and equipment. So far they've been joined by the Rural Fire Service, State Emergency Service, Fire and Rescue NSW, and Mudgee Rescue Squad - and Highway Patrol Police are also visitors.
"What's pleasing to see is the emergency services have been coming to us because of the interest they get from the public by coming along," Mr Maurice said.
December's guests are Mid West Security, who have tips on keeping your prized vehicle safe. And with the VVPPAA unavailable, the award-winning Gulgong Butchery will be on the barbecue.
