Directly across the street from the old Fisher Automobile complex and the present day Kroger supermarket on Michigan, was the Cadillac Co. of Indiana/Automobile College. Located at at 500 N. Capitol, it was built in 1910 and besides the Cadillac dealership on its first floor, on the second floor was the college that was reputed to be one of the first “technical” schools related to autos in the country. 

Now PlasmaCare Indianapolis, it is a busy blood plasma donation center.
