I agree with you in the sense that alignments sell themselves and most of the cars on the road are probably out of adjustment
That said, my mom’s car wears tires evenly, isn’t pulling and the steering wheel is straight
So that’s good enough for her, I decided.
One of my own cars from several years ago, the steering wheel had always been slightly off-center, from day one. Yet it wore tires evenly, no pulling, no squealing. I easily got 80K out of the tires. The only reason I got new tires is because they were a few years old, and were starting to dry rot. They still had an acceptable amount of tread left, IMO. An alignment wouldn’t have gained me much, but I was advised to do it. I politely declined
But I have had cars that did clearly need an alignment, because the tires were wearing unevenly, and there was a pull. I happily paid for an alignment . . . no parts needed, BTW . . . and the problem was resolved. Naturally I also put on new tires and that new set did wear evenly.
I’m not comfortable with doing my own tires at work, because I’m worried that some self-righteous POS might be convinced I’m stealing tires from our warehouse and mounting them on my own car, never mind we don’t even have my size in stock . . . !
Our fleet doesn’t do in-house alignments, not that I’m aware of, FWIW. We farm it out to a local shop that only does front end work, tires, rims, alignments, etc. They seem to do acceptable work, but nowhere near the skill level of your guy
