(11 Oct 2015, 6:28 pm)S813 FVK wrote I don't see what difference a year would make (ie 2000 renowns replacing the 1999 ones). I'd imagine the Fab 57 renowns will get withdrawn directly (that is if the Citaros do replace them).
Younger vehicles have a higher book value than older vehicles. If the "Fab Fifty Seven" branded Volvo B10BLEs still have quite a high book value, they will need to remain in the fleet beyond this year, and they will also have the cost of the DDA modifications to cover too.
I believe there's a substantial difference between those Scania OmniDekkas new in 2003 and those new in 2004, which perhaps explains why the latter examples are also being re-trimmed, as they'll have to spend longer in the fleet to depreciate the entire book value.
