The metric that matters most is vehicle availability: the percentage of your fleet that is road-ready at the start of a shift. It is simple, it is hard to game, and it maps directly to revenue.
Second is mean time between failures, tracked per unit rather than per fleet. Fleet averages hide the handful of problem units that generate most of your cost.
Third is first-visit fix rate. A repair that needs a second visit costs roughly double, and the second visit is almost always caused by an incomplete diagnosis rather than a difficult repair.
Fourth is PM compliance rate — the percentage of scheduled services performed within their window. The three not worth tracking: total work orders, average repair cost, and technician hours. All three go up when things are going well and up when things are going badly.
