Ards Bus Preservation IBZ3051, Dún Laoghaire Harbour, 28-10-2017
Not everyone's favourite, but the Mercedes-Benz midis developed routes which had previously had either infrequent big bus services, or which had been operated by smaller midis whose success had outgrown them. One operator I recall in Nottingham used to advertise "Travel to work in a Mercedes!" on their timetables - cheeky, but effective!
This 609D is now in the care of the Ards Bus Preservation Group. I presume Flexibus was some sort of demand responsive service.
