Introducedin the summer of 1905, the Model C was a mid-year offering, at a reduced price. It was a single cylinder Model B with a Model F “hood” and radiator. Cadillac called the Model C “an accommodation to customers who want a detachable tonneau.” The tonneau of the Model F was non-detachable. The introduction of the Model C may be interpreted as “a program to move out the remaining chassis.”

Lower ratios for runabout to be run on smooth, level roads to higher ratios for loaded Delivery to be run on rough, hilly roads. Instructions for changing sprockets were furnished to owners, but the change involved disassembly of the transmission and rear axle — definitely not a “quick-change” setup.
