 After the former company took over the latter in 1971, the Gräf & Stift name remained in use as an MAN brand for the Austrian market and for trolleybuses until 2001, when ÖAF-Gräf & Stift AG was renamed MAN Sonderfahrzeuge AG.With the retirement of large numbers of Gräf & Stift vehicles since the start of the 21st century, the MAN/Gräf & Stift portion of the fleet has been now much reduced.Some of the retired Salzburg vehicles were sold to other trolleybus operators.
