Arriva is the one out of the big three bus operating groups that is not normally seen in Saddleworth, although the aquamarine and stone livery characteristic of that group was visible for a few years on some class 142 Pacer units that served Greenfield station, ironically only after they ceased to be operated by Arriva. Hence the interest caused by the appearance of some Metrobuses from Merseyside in this livery. Stott's must have needed them urgently as they didn't normally operate buses in their previous operator's colours. F819 YLV was new as Merseyside PTE 819 and is seen on 6th January 2004.
