The 1930 Bentley 4-litre saloon that was featured in Driven and spent most of its life in New South Wales is leaving Australia after selling for A$462,000 ($592,000) at auction.
The Bentley had been expected to sell for A$100,000 less than that at Shannons' Sydney autumn auction on Monday, but easily passed its reserve.
It was initially pursued by several bidders before its future ownership developed into a telephone slugging duel between two overseas enthusiasts.
The Bentley came from the estate of the late Mosman, Sydney, sewing machine importer and avid Bentley enthusiast Alan Mingaye, who found the car lying partially disassembled under a tree in Turramurra, New South Wales, in 1957.
It had a full body-off-chassis restoration in 1980, but because of Mingaye's ill health it had not been driven regularly since 1988.
