Compass have a few old minibuses parked at DiagTest, as well as the preserved Economic vehicle. Just because Arriva park in there too, doesn't mean they're part of the same depot. Unit 4 is reportedly used by the Metrocentre to store things, does that mean those things are Arriva's too? In summary; Units 1-3 are Arriva, Units 4 and 5 are not.
