They seem to be getting a mixture of Enviro 400s. Think E65 along with E64 were the oldest of them (57 plates), the rest seem to be 08 / 09 plates. Two that came up recently are in original Go-Ahead London livery with the charcoal grey skirt as portrayed by E65 at Metrocentre today. There is another (E64 I assume) in GAL original livery and an all red one in Saltmeadows facing away from the gate.

Dan can you provide us with a list of registrations and possible fleetnumbers for those who keep their own records please.
