A 1930 Cadillac V-16 Roadster by Fleetwood made $1.1m at RM Auctions' October 9-10 sale in Hershey, Pennsylvania.
A total of 54 were produced at the outset of the depression, a feat made possible by the patronage of Cadillac's parent company, General Motors.
 This 1930 Cadillac V-16 Roadster was built for a wealthy family from Massachusetts |
The present lot was built for the wealthy Whittall family, who owned a number of mills in Massachusetts, and is sold along with its original build sheet.
It remains in exceptional condition despite its age, having been in storage since the early 1950s. It was fully restored in 1990.
A 1905 FIAT 60 HP five-passenger tourer by Quinby & Co also sold well, realising $825,000.
The lot is the only surviving example of the 20 originals and was formerly owned by a member of the Anheuser-Busch family.
It's considered the first true luxury automobile. The chassis retailed for $14,500 at the time of production - a figure that equates to around $370,314 after inflation.
A 1933 Chrysler CL Imperial dual-windshield Phaeton by LeBaron, one of 17 in the world, sold for $522,500.
LeBaron Carrossiers were among the most fashionable coachbuilders of the 1920s and 1930s, perhaps best known for their elaborate designs for Duesenberg.
RM Auctions' next sale takes place in Texas on November 15 and features a 1967 Shelby 427 Cobra.
