Shame the 829x and 83xx only have 3 years left although some are getting quite bad, the 15 year old B10's should be withdrawn this year but that won't happen, hopefully the Versa's will take the role of the "Spare Fleet".
Don't bother with maths on a morning, eh?
They're 7 years old, so (should) have five years left in the fleet. Obviously some buses are retained for longer - prime example being the Volvo B10BLEs and Volvo Olympians. If reliability becomes a concern, they should be withdrawn in accordance with their predicted life span, to allow reduced engineering costs.
