Stagecoach retrimmed their DTVs, too.
For a bus which is effectively a classroom for 6/7 hours a day, it makes sense to tidy it up inside and make it clean and comfortable. New starters don't just sit in the drivers seat.
It doesn't look finished yet either, with extra mirrors missing etc. Perhaps retrimming the entire bus worked out cheaper when buying it, and the seats can be used as spares when they're removed?
