A selection of nine American motorcars from the famed collection of Eugene Beardslee will join the much-anticipated the Greenwich Concours d'Elegance Motorcar Auction on June 3, 2012.

Eugene Beardslee, the founder of Beardslee Transmission and a passionate collector of original classics, was devoted to the pursuit of the finest classic cars in the world.

A highlight from the collection, a 1939 Cadillac Series 90 Sixteen Formal Sedan, is one of only eight built in this body style. This handsome and rare Cadillac is the eighth and final Fleetwood 9033F Formal Sedan built upon a 1939 V-16 chassis.

The car was originally purchased by the Calumet Farms Family of Lexington, KY, the famous breeders of eight Kentucky Derby winning horses, and it remained in the family's possession until the late 1970s when ownership passed to Beardslee. The vehicle is expected to fetch £48,030 to £64,040.

According to Bonhams' website, Gene Beardslee was not one to compromise in any way on the restoration of his classic motorcars. His 1957 Lincoln Premiere Convertible, the finest convertible available from Ford Motor Company that year, was no exception. The striking convertible with its two-toned red and black interior and a self-locking "Robotic" power top is estimated to fetch around £57,636 to £76,849.

"Bonhams is excited to offer this group of classic motorcars from the fine Beardslee Collection at this year's Greenwich auction," Rupert Banner, Bonhams Motorcar specialist stated. "All of these motorcars have been carefully protected in climate controlled storage, and the in keeping with their Father's high standards, his descendants have invested the time and resources to bring the cars to top operating condition," he explained.

Another example of the high caliber of American classics on offer from this prestigious ownership is the 1938 Lincoln Zephyr 4-Door Convertible. Finished in deep rich lacquer paint and trimmed in tan leather, it is one of only 461 built. This car features the trendsetting frontal design that would be adopted by virtually every American car manufacturer within two years, a futuristic interior look.
