Close to 700 vehicles were on display at Jack Brabham Park on Saturday for what was described as the biggest Gnoo Blas Classic Car Show.
Organiser Denis Gregory said there were more than 600 cars and about 30 trucks and 30 motorbikes on show.
"This would be the biggest yet," Mr Gregory said.
"The car clubs from the South Coast said they couldn't come because of the fires, we probably lost 30 to 40 cars."
Mr Gregory said vehicle owners came from across the Central West as well as Newcastle, Canberra and Sydney.
"They've come from about 115 different post codes, we are rating it now as one of the [biggest events] in Orange," he said.
"We've got 30 categories and I would hate the judge's job to pick 30 winners.
"Most of these cars are better now than they were."
When it came to spectators he said it was estimated that about 5000 people visited the event.
Mr Gregory said this year's show celebrated the 60th anniversary of the old Gnoo Blas track hosting the first Australian Touring Car Championship race in 1960.
To celebrate the anniversary, a dinner was to be held at Orange Ex-Services' Club with 280 guests including five former drivers who competed in the Australian Touring Car Championship, one of whom was Mr Gregory.

"The car we raced was what we drove to work on the Monday," Mr Gregory said.
"They didn't have the brakes of the modern cars, they didn't have the tyres.
"I had a Morris Minor, then a Morris Major, I raced both of them."
However, he said Jaguars were driving at 135 miles and hour on the road racing circuit.
Another one of those drivers in the first first Australian Touring Car Championship race was Kevin Bartlett who had previously been racing his Morris Minor at other events at Jack Brabham Park.
"I was only young then, only 18 to 19 years old and working on my own car doing my own thing," he said.
However, Mr Bartlett's racing career included all stages of racing in Australia and internationally from 1957 until he retired in 2006.
"I went through all the stages from the smallest little touring cars you could possibly race to the fastest cars you could race in the country in the formula 5000."
Among those who attended the event was Amanda Steenkamp and Flavio Booth who were new residents to Orange and wanted to see the Mustangs.
Shaun Baigent and his family attended the show as part of the Dubbo Antique Auto Club.
"We've got a car with us," he said.
"We came here last year, the club has been down here for a few years."
