Chassis AM300/3/1564 is a 1958 Aston Martin DB Mark III, a left-hand-drive fixed-head coupé representing the final and most refined evolution of the David Brown DB2 lineage. Delivered new to the celebrated S.H. Arnolt dealership in Chicago on 23 June 1958, it passed to a single Michigan owner who retained it for over five decades. Powered by the twin-cam three-litre DBA straight-six, it features the model's distinctive grille derived from the DB3S racers and was among the first Aston Martins equipped with front disc brakes.
