In 1977, the CTA placed its last order for New Look buses from GM. This order, which included 200 buses, made for a total of 1,870 GM New Look buses purchased since 1972.

The buses were painted in the CTA’s two-tone green scheme, although some where eventually repainted in the CTA’s white, red, and blue paint scheme which was introduced in 1987.

While portions of the 9600-series were retired throughout 1990 and 1991, the entire series was not retired until 1996.
