This 1992 Volgren bodied Mercedes OH1418, 10 (1110AO), is seen visiting SITA's Footscray depot in August 2008. The driver is under instruction and it was probably two jobs in one: driver training and delivery to or from SITA.
 
Older Mercedes were still going strong in March 2014. Seen at the Airport West depot is 29 (1129AO) a 1991 Volgren bodied Mercedes O405 acquired from Kastoria Bus Lines where it was 12 (1412AO). It was acquired with 28 (1128AO), which may be the bus behind - Kastoria 21 (1421AO) - both are now retired.

Similar Volgren/Mercedes 8 (1108AO) also swings on to the stands at Moonee Ponds.
 
In the highly standardised fleet, at least Volgren 20 (1120AO) had a slightly different ad for the VW Polo on its rear in this Moonee Ponds line up.
