Most operators feel it before they can explain it. Somewhere around 60,000 miles, a van that was running fine starts costing more. Oil changes, sure — but then brakes. Then tires again sooner than expected. Then something bigger.
It's not bad luck. It's the maintenance escalation curve, and it's predictable.
At 60,000 miles, most commercial delivery vans exit the zone where routine service dominates the maintenance spend. Brake components on vehicles doing 25-30 stops per day wear faster than manufacturer schedules assume. Suspension and steering components on pothole-heavy urban routes start showing wear. The cumulative effect of 60,000 miles of stop-and-go, heavy loading, and curb strikes adds up.
What the data shows: Operators tracking maintenance cost per mile consistently report a step-up of 25-40% in the 60,000-80,000 mile range across ProMaster, Transit, and Sprinter platforms. The Sprinter tends to hit harder — Mercedes parts premiums compound every repair.
What to do about it: The mistake most operators make is waiting for the repair to decide. By then you're reactive — vehicle down, driver idle, emergency shop rate. The operators managing this well are identifying vehicles approaching 55,000-58,000 miles and making a deliberate choice: trade now while equity is still favorable, or build a maintenance reserve and plan a defined service schedule through the escalation zone.
There's no universal right answer. It depends on your equity position, your financing rate, and whether the new vehicle capacity justifies the carrying cost. But the decision should be made at 55,000 miles, not 65,000.
