A collection of vintage vehicles will be on display in the Highlands this weekend at Berrima District Historic Vehicle Club's annual Berrima Rally.

Historic vehicles will descend on Mittagong for the event, to be held at Mittagong Public School tomorrow and Mittagong RSL Club car park on Sunday.

Club president John Holton said the event was called the Berrima Rally because it was named after the club, even though it would be held at Mittagong.

Mr Holton said the rally was the club's biggest event on their calendar and attracted cars and members of affiliate clubs from as far as southern Queensland and northern Victoria to the Highlands.

"For about 37 years the club has been holding the rally," he said.

Between 9am and 1.30pm tomorrow, the cars will be lined up for viewing and judging at Mittagong Public School, with a prize awarded to the best vehicle from each decade from the beginning of the 20th Century to the 1980s.

"We do it differently to other clubs, the members vote for the winners," Mr Holton said.

He said community members would be welcome to look at the line-up of vintage vehicles and chat with the owners.

"The thing about Berrima District Historic Vehicle Club is that we don't just have cars, we have bikes and trucks and all sorts of historic vehicles.

"We pride ourselves on inviting everyone along."

Mr Holton said one of the big draw cards of the event would be a 1904 model Renault.

"It's just picture perfect.

"There'll be some cars there that people have never seen before."

He said there would also be historic displays and a live band at the rally tomorrow, which would go ahead rain, hail or shine.

At 8.30am on Sunday the vehicles will gather at Mittagong RSL Club car park to receive route instructions for the club's scenic run, before awards and trophies are presented between 12.30pm and 2pm.

Mr Holton said the club was always looking for new members and anyone that owns a vehicle 30-years-old or older should consider signing up.

"The club has a terrific social side."
