A 1929-’32 Bentley to Become Most Expensive Bentley Sold at an Auction image

The Bonhams’ Goodwood auction in June is expected to sell the most expensive Bentley ever sold at an auction, a 1929-’32 Bentley 4 1/2-litre. The car is expected to fetch the breathtaking sum of $6.3 million.

The current record is held by another Bentley, a 1930 Bentley Speed Six Tourer sold in 2004 for $5.1 million, according to media reports. The auction will present a collection of seven cars and two motorcycles that belonged to George Daniels, a British watchmaker who died last year, and it is expected to sell for $12.6 million.

The focus point of the auction is this amazing red Bentley, a supercharged single-seater, once owned by Sir Henry Birkin, who set the Brooklands Outer Circuit Lap record at more than 137 mph in 1931. The car was nicknamed the Brooklands Battleship, and it finished first in the 1929 Brooklands Six Hour Race and 500 Mile Race, and also claimed victories in the 1929 Irish Grand Prix and 1929 Tourist Trophy.

Mr. Daniels drove his cars frequently and participated in heritage races. The Birkin car was a favorite.

“For all its inconvenience it is a most exhilarating car to drive both on the road and track,” he wrote.
