"Its really good to put Martinborough on the map -- some businesses said they'd done their biggest trading ever. It's a great feeling to start something and have it be a bigger success than the first time."
Mr Pivac said he was inspired to run the event as he was constantly meetings fans of vintage American cars.
"I think it's a Wairarapa thing -- it was surprising how many people have a classic vehicle," Mr Pivac, who owns a Chevrolet Apache pick-up truck, said.
"I kept talking to my friends about doing a rally, and it got to the point where I'd talked about it so much, I'd better do it.
"Organising it was scary at first -- but now it's just fun."
He said some of the highlights of this year's event were the car display at The Farriers in Masterton, which "filled the carpark to the brim" and a twilight race at the Masterton Motorplex -- a new addition to the itinerary.
"The drag strip was completely new for a lot of people. They had a lot of fun racing, even with slow cars -- although some of them performed quite well on the track. People went away with big smiles."
Other events included a drive-in movie screening at Martinborough Rugby Club, and a motorcade tour of "cool sites" around the Wairarapa countryside.
Also popular was a fashion show of 50s and 60s pin-up clothes organised by Martinborough boutique, Jessica's Living Room.
"That really suited the Americana feel," Mr Pivac said.
"There were a good few hundred people gathered around to watch."
BP Martinborough was also a loyal supporter, running a prize draw for participants who came to fill up.
Mr Pivac said visitors particularly enjoyed the event's "relaxed atmosphere".
"If it gets too big, it could lose that relaxed feeling -- but we are hoping to have at least 300 cars next year, and another thousand people."
