"Briefly I would like to calculate...the wisest way of running a fleet, including the policy of vehicle replacement." This is the gist of a recent inquiry.
This and allied queries have been repeatedly dealt with in this series of articles.

The Commerial Motor Tables of Operating costs ", a mileage life of 150.000 is reckoned for quantityproduced vehicles and 300,000 for quality-produced vehicles.
