Building #3 of the original Duesenberg factory on South Harding St. is still intact, now housing the Indianapolis Public Transportation Corporation. 
Duesenberg, maker of luxury coachbuilt cars, suffered during the depression and folded in 1937. The complex was later used by Marmon-Herrington and American LaFrance companies for bus and truck manufacturing.
