Hong Kong Buses - KMB's rarer double deckers

We take a look at some KMB double deck classes numbering less than 100 each. These include: AMC, AMN, ASU, ATEU, ATH, ATSE and AVBWS. To the casual observer, the KMB fleet is highly standardised, but this video begs to differ.
PS - I haven't included the Neoplans in this video, as there are rather too many of them to count as a rarity (162). The single deckers (by definition, a rarity in the KMB fleet) have a video of their own.
