He arrived ten minutes early and waited outside her office while students hurried down the hallway with books under their arms. The university building smelled of floor cleaner and photocopier toner, and Calvin felt oddly out of place in his work jacket. Then Holden appeared, shook his hand, and led him into a room crowded with reports, conference badges, and a whiteboard covered in equations. "You said you had questions about the service-access variable," she began. Calvin opened his notebook and showed her all seventeen.
Her scheduled hour became two. Calvin asked whether her comparisons controlled for age and usage, how travel times were recorded, whether the labor figures included expensive diagnostic subscriptions, and whether the analysis distinguished simple repairs from electronically protected procedures. Holden answered with the pleasure of someone who had spent months trying to persuade readers that the assumptions mattered more than the headline results. In some modeled conditions, she explained, closed diagnostic architectures could generate service costs one hundred eighty to two hundred forty percent higher than comparable arrangements that allowed wider independent competition over a seven-to-ten-year horizon. That did not mean every piece of equipment would become equally expensive or that any single manufacturer would follow the model exactly.
"Those are scenarios," Holden said, circling a paragraph with her pencil. "The outcome depends on implementation, dealer behavior, competition, the mix of repairs, and the buyer's ability to negotiate." Calvin nodded. "A cooperative with forty machines isn't an average buyer, but it isn't big enough to dictate the market on its own either." Holden agreed and added another factor he had not considered fully: the true bargaining power of a customer came from its ability to choose an alternative, and software-dependent equipment could reduce that power after purchase. They spent the last half hour mapping what information he would need to determine whether the model applied to western Kansas.
On the drive home, he stopped for fuel and stood beside his pickup while the wind pushed grit across the concrete. A young farmer two pumps over was complaining about the cost of replacing a sensor that had failed just after the warranty expired. The farmer believed the hardware itself cost almost nothing and could not understand why diagnosis required a separate service trip. Calvin did not assume the anecdote proved anything about the transition he was investigating. He simply wrote it down later as one more example of how repair cost and component cost could become entirely different questions.
By June, Calvin began visiting independent mechanics. He did not arrange a formal study, issue questionnaires, or tell them he was considering canceling a major purchase. He drove to workshops he already trusted and asked them to show him the work they could do today and the work for which they now needed outside authorization. At the first shop, the mechanic opened an older machine's service access without difficulty and then showed Calvin a newer fault-code interface that displayed information but would not permit certain calibrations. The mechanic was annoyed less by the existence of software than by the growing distinction between understanding a fault and being allowed to complete the approved repair.
