Standard Agora buses have been used by Athens bus operator OAS in two versions: diesel and CNG. The range consisted of: * Standard 12-metre "S" version, available in two- or three-door form * Articulated 18-metre "L" version in three- or four-door form * "Line" 12-metre version in two- or three-door form (built from 1999). This version is distinct from the standard Agora by its engine layout, which is longitudinally-mounted (under the rear passenger seats) instead of being transverserly mounted in the Agora S and L. That gives the Line version a slightly greater seating capacity and a better fuel economy over the S version. * Intercity version called "Moovy" (unveiled in 2003) which was based on the Agora Line.
