1931 Bentley 4.5–Litre Supercharged Tourer

Estimated value from $2.6 million to $3.3 million

If you love Bentleys, you want a Bentley 4.5–Litre Supercharged Tourer—otherwise known as a Bentley Blower. Scorned by W.O. Bentley, who believed that adding a supercharger (aka a “blower”) to his creation would “pervert its design and corrupt its performance,” the car has a fan base that begs to differ.

Bonhams sold the greatest of the 50-odd Bentley Blowers at Goodwood in 2012—Sir Henry “Tim” Birkin’s own machine, which fetched $3.5 million. This example is one of five that originally had saloon coachwork, and it has matching chassis, engine, and registration numbers. The approach of the marque’s 100th anniversary, due in 2019, makes the car that much more attractive to bidders.
