After only twelve years of production the 30,000th Mercedes-Benz has been rolled out. It’s a number that is unique among urban buses and stands for the wide-reaching success of a flexible modular system. On 25 August 2010, Michael Göpfarth, Executive Managing Director of Mercedes-Benz Buses and Coaches of EvoBus GmbH, presented the milestone vehicle to Walter Rathberger and Erich Haider, board members and managing directors of Linz Linien GmbH. In his speech he praised the Citaro’s ability to stay flexible and modern throughout the years. "The Citaro has always known how to set trends among the regular service buses. It continually integrates technical and visual developments into its production. In public transport systems they offer a high degree of economy and reliability and they provide passengers with an attractive form of transport. Virtually all the customer wishes that one could imagine are represented by the Citaro."

The majority of the 30,000 Citaro buses produced came from the Mercedes-Benz bus plant in Mannheim, where the Citaro has been built since 1998. At the end of 2009, 3530 staff on a production area covering 141,000 square metres were working to produce Mercedes-Benz urban and rural service buses and touring coaches adorned with the trademark star.
