Shortly later, MAN's competitor Daimler was designing the Mercedes-Benz O405 in 1984 to fit with the new Standard-Bus requirements, and this model spread quickly in the market in the late 1980s.
Based on the Standard-Bus model, a number of variants were developed by their respective manufacturers - here, it was the Kässbohrer Setra S 300 NC to show the first a low-floor version in 1987 that was sold since 1989.
