It would make sense for them to cut their losses while they're still worth something, especially with the 63 plates.

I remember my days at Arriva London, witnessing our B9s which are 61 plates being converted to Euro6. The B9 will retain its book value regardless of how expensive it can be to run because they're so robust and very reliable. There was a time when nearly every new  Go-Ahead London bus was a B9TL. It's sad to see it not in production anymore but I can't see them getting rid of any B9 before the Omnidekkas depart. Especially the Cobalt and Coast which if I'm not wrong are high-spec.
