The terms repair and maintenance are often confused or used interchangeably. I find that somewhat uncomfortable because I like precision in terminology and definitions — and in this case, the distinction is actually useful. Here is a good definition: Repair is corrective work performed to eliminate an existing fault, restore lost function, or correct damage that has already occurred. Maintenance is preventive work performed to preserve function, reduce deterioration, and pr

Someone recently asked me an interesting question: Is it difficult to repair vehicles without an assistant? After all, sometimes you need someone to hold or pull something, watch from another angle, or press a pedal while you inspect the vehicle. How can you do it all on your own? In reality, that is not the main difficulty of working alone. In the vast majority of cases, one person can repair a passenger vehicle without much trouble. An inventive mind can almost always find

In automotive repair, you're dealing with retail customers who are expected to make technical decisions about machines they know very little about. At the same time, they approach repairs with the same price-shopping mentality they use when buying products at retail stores. That creates an inherently inefficient business model. A significant portion of a technician's working time is spent managing expectations, explaining technical issues, preparing estimates, obtaining appro

In automotive repair, we routinely operate within incomplete, outdated, or outright incorrect technical information, and yet we are expected to assume full responsibility for the decisions we make. That responsibility may be financial, professional, moral, or reputational. Sometimes it manifests in only one dimension; sometimes it converges in all of them at once. Regardless of the form, it remains personal. If the repair succeeds, the outcome is treated as ordinary. If it fa

I don’t have much to add here — he’s saying almost exactly what I would say on this topic. If the time, effort, and knowledge that diagnostic technicians invest in developing their skills are not properly paid for by customers, there simply won’t be any diagnosticians left in the industry. Outside of a few rare hobbyists, no one is interested in consistently working for free. And if you don’t know who ScannerDanner is, it’s worth looking him up.

The Comfortable Explanation Most people believe they understand how automotive service works. They assume labor rates rise because mechanics want more money. They assume technician wages remain low because shop owners or dealers are greedy. They assume delays, burnout, and declining service quality are caused by a “shortage of technicians.” These explanations feel intuitive. They assign responsibility to visible actors. They fit neatly into familiar moral categories: workers

There is visible work in an auto repair shop. This is the work customers see, recognize, and instinctively associate with what an auto repair shop does . The stereotypical idea of “turning wrenches”: replacing parts, fixing what’s broken, draining and refilling fluids, removing something that failed and installing something that works. This is the work customers expect to pay for. And, in most cases, this is the only work they believe they should be paying for. Everything e

The short answer is no. Not “it depends. ”Not “with the right mindset.” Simply no. And this is not a new conclusion. The same answer would have been correct in 2025, in 2024, and for many years before that. I am in my early fifties, and whatever brief historical window in which becoming an automotive mechanic may have been a rational economic choice appears to have closed before I ever entered the profession myself. This text is not about personal fulfillment, craftsmanship,

Part 1. What the Industry Usually Means by “Training” In the automotive service industry, training is commonly presented as the primary solution to a wide range of problems: technician shortages, diagnostic errors, quality inconsistencies, and even low customer satisfaction. The underlying assumption is simple: if technicians are trained more, outcomes will improve. However, this assumption is rarely examined in terms of efficiency , transfer of knowledge , or economic cost

In many service industries, the most accurate answer a professional can give is also the least acceptable one: “I don’t know yet. ” Not because the professional lacks competence, but because the system demands certainty before understanding exists. Over time, this mismatch has produced a quiet but powerful selection effect. Markets have not optimized for accuracy, responsibility, or truthfulness. They have optimized for confidence, speed, and promises. And in doing so, they h

A very common situation in automotive repair looks like this. A customer visits one shop. The vehicle is inspected, and the conclusion is given: “This part is bad. It needs to be replaced.” The customer then begins shopping by price. They go to another shop and ask: “Can you just replace this part? The other shop already diagnosed it.” From the outside, this sounds reasonable. From the inside, this is where problems begin. Split Responsibility Explained Split responsibility

The Myth of the Technician Shortage In recent years, public discourse has increasingly centered on a supposed “shortage of technicians” in the automotive service industry. This idea is no longer confined to trade publications or internal industry conversations. It appears regularly in mainstream media, surfaces easily through basic online searches, and is frequently presented not as a hypothesis but as an established fact. In some cases, it is even repeated in television inte

In the long run, the cheapest repair or maintenance job is usually the one done with the best parts and the best work you can get. Sure, the upfront cost might be higher. But cheap parts wear out faster, don’t fit right, or give you grief the next time you have to take them apart — all of which means more labor and more money later. Cheap labor isn’t really cheap either: it often means rushed jobs, corners cut, or someone with less skill trying to hit unrealistic timeframes.

Whoa — I just realized my last blog post here was three years ago! I can’t really promise I’ll be posting more often; that all depends on how much free time I can find — and there hasn’t been much of that over the past few years. As far as I can recall, the only real change to this site during that time was the addition of a “compliance logo.” Yes, apparently the government even dictates what kind of logo I’m allowed to use on my own business website. Amazing, isn’t it? S

What are the benefits of working with a personal mechanic? 1. Continuity of Care When you bring your vehicle for inspection, maintenance, or repair, it is handled by the same professional every time. Over the years, that creates familiarity with your vehicle’s history, patterns, and quirks. Ideally, the best person to maintain a vehicle is its owner — if properly equipped and experienced. A personal mechanic is the next best alternative. In many cases, I know more about some
