But Roz Bradbury, who also owns Sunbury Ford in north-west Melbourne, says having a piece of the country's automobile history is worth the price.

The Saturday afternoon auction came after Ford shut down its Broadmeadows plant last week.

Mr and Mrs Bradbury paid $122,000 to buy a winter white Sprint XR6 Ford Falcon sedan - the last of the 500 models to roll off the plant.

The sedan is usually priced at $65,000.

The couple also picked up a smoke grey Ford Falcon ute XR6 for $82,000 - a mere $17,000  above the retail price.

In a statement, Ford pledged to maintain ownership of the final, non-registered and non saleable Falcon, Falcon ute and Territory.

They said the vehicles will be displayed at events and loaned to museums in Victoria in the longer term.

The American car company also auctioned a silver Territory for $68,500 and a Ford blue XR6 Falcon sedan for $81,500 to a Boronia man.

Ford raised $353,000 from the auction, which they say will go towards robotics programs in Geelong and Broadmeadows.

Mr Bradbury said the Avalon Airport auction attracted about 1000 people.

The couple said they had no intention to buy when they went to the auction, but got swept up in the excitement.

"It was very emotional," he said.

"There were so many people in the room it was extraordinary."

Mrs Bradbury said the Ford Falcon ute was an "incredibly powerful vehicle" and was "much sought after".

The couple said they would not drive the vehicles, but Mrs Bradbury planned to display them at the Sunbury showroom.

"To have the last ever ute produced at Broadmeadows is something we are very proud of," she said.

"It is the very last of the iconic model and car ... we saw it as an opportunity to be able to purchase a piece of Australian history."
