The vehicle display on the lawns of the historic house was part of the Riviera Owners' Association biennial national meet, which started in Bathurst on Thursday.

Classic Rivieras from 1963 to 1984 were on display, as well as locals cars from the Bathurst Historic Car Club.

Event co-ordinators Brian and Linda Hall said more than 60 people had travelled from right across Australia to attend the third national meet.

"People have travelled from South Australia, Tasmania, Queensland, Victoria and NSW," Mrs Hall said.

"Previously we have met in Griffith and Coffs Harbour. We always get people coming from all over the place."

The pair, who themselves hail from Queensland, noted that Buick Rivieras were few and far between in Australia.

"Rivieras are pretty rare. There are only 75 in the owners' association in Australia so to get 30 here is quite incredible," Mr Hall said.

He added that he had had a lifelong love for the classic American car.

"I was pretty much born into one, my grandfather bought a Buick in 1920 and I bought my first one in 1978," he said.

"I love them because I grew up with them and they're different you don't see many in Australia."

Mrs Hall said that Bathurst was chosen for the third national meet because it was a central location for members and because it had plenty of local attractions to visit.

She said those in town for the national meet have enjoyed a spin around Mount Panorama, visited the National Motor Racing Museum and Stone Pine Distillery, and toured O'Connell and Portland.

Mr Hall said that a new location was chosen for each meet so that people could get out and explore somewhere new.

He noted that he thoroughly enjoyed his spin around Mount Panorama and added that Abercrombie House was the perfect spot for a Show and Shine.

"It's ideal, just magic and it's beautiful to be able to look out and see all the scenery."

Mr Hall noted that everyone had really enjoyed their trip to Bathurst and said there was great camaraderie among the group.

"The first time people meet up they come for the cars, then from then on it's for the people because you make good friends."
