What was wrong with Stockton MAN ALX300 22061 that led to it being put on the disposal list?

Anyways, it is now safely in the hands of the Teesside 500 Group according to their Facebook page which is great to hear.

However, as it was delivered new in the Beachball swoops livery, it may easily end up being mistaken for an active service vehicle when used at rallies until the old corporate livery is completely phased out.
