It isn't a discontinued product yet, is it?No idea if it has been discontinued.
Imagine it would be diffcult to justify the purchase of one brand new EcoCity though.
Highly doubt Arriva would buy one, if it is still available to buy unless they were maybe to buy some for different routes at Darlington depot but there isn't really any routes they could use them on, possibly the 1/5/5A at a push.
