1931 BENTLEY 4½-LITER SUPERCHARGED TOURER
SOLD: £2,017,500 ($2,669,500*)
Bentley’s 4½-Liter is one of the brand’s most celebrated models, but by 1929, it was in danger of being outclassed by Alfa Romeo and others. Bentley Boy Sir Henry Birkin decided a little forced induction would help the car’s chances and commissioned a run of 50 “Blower Bentleys,” 4½-Liter cars with a supercharger added. These were built to homologate five race cars that Birkin campaigned across Europe and were capable of more than 100 mph—serious performance for the time. With just 50 built, they don’t surface often. We’ll call its price market correct.
