Your car maintenance you'll typically spend 4 hours for an annual service, at $50 per hour. Total: $200
A bus in a depot uses in house staff ($25 per hour), and since all the busses are identical and they're probably performing the same service on 5 at a time, probably only works out to an hour per bus. Total cost $25.
Thats so small compared to the salary of the driver who drives it around normally, maintenance cost might not be a significant part of the equation.
