A 1930 Duesenberg Model J "disappearing top" roadster sold for £1.8m ($2.7m) on the weekend. That is a record for a car sold at a Danish auction.
The vehicle, which features a retractable canvas roof, was the lead lot of Bonhams' sale of the Frederiksen collection in Ebeltoft on September 26.
Duesenbergs are among the most coveted cars at auction, with this example particularly desirable.
"This Duesenberg not only represents the supreme classic expression of the Model J, it is also one of the most deeply original examples left in the world today and gifted with an unbroken chain of ownership since it left the Duesenberg factory 85 years ago," explains Bonhams.
The record for a Duesenberg is $10.3m, set by a Model J long wheelbase coupe in 2011.
A 1914 Mercedes 28-95 Phaeton made £923,152 ($1.4m), while a 1939 Lagonda LG6 Rapide Drophead achieved £538,033 ($817,291).
The collection - described by Bonhams as one of Europe's most important - was amassed by Dane Henrik Frederiksen over several decades.
"I think cars are a kind of art, I think they're beautiful," said Frederiksen prior to the auction.
"I've always bought with the heart and not with the brain. I've never sold a car before, so this is a first for me."
Frederiksen will today be fully aware of the investment potential of rare motor cars, particularly ones in immaculate condition.
Classic vehicles have grown in value by 9% since the start of the year, according to Historic Automobile Group international.
