You could have worked at the shop I’ve been going to for the last 30+ years. Totally how they do it. Plus, the owner will talk your ear off about life stuff every time. Nothing to do with cars.
Shops like that seem to be few and far between these days. There's not many young guys getting into the trade and it's kinda sad. Keep going to them as long as they stay in business, but eventually they're going to retire and the new crew will take over.
There's a shop about 3 miles from my house that's made up of mostly guys my age (58) and they're always busy. I stop in occasionally for an alignment or a State Inspection (can't do either at my house) and these guys are laid back and honest....... they even offered me a part time job and while I was honored, I passed for now.
My old shop is a cluster....... one tech I worked with is still there and he's ready to bail, and after 25 year's it's sad that they don't respect him for his talent...... instead he's seen as an overpaid liability and the new corporate mentality is we can get anyone to change parts for slightly above minimum wage with a paltry incentive program.
That's all great and maybe anyone can hang parts, it's knowing what parts need to be replaced so you're not stuck with comebacks and a pissed off customer.
Unlike the AutoZone ads that show the counter jockey pulling a code and selling you a part, it's not like that on the real world. We used to see the Ford Windstar vans come in with lean codes and 4 shiny new AutoZone 02 sensors..... the problem was the intake manifold gaskets and the forward valve cover...... Ford had a TSB out with a part # for the updated kit to fix this issue, but AutoZone insisted on selling parts after the "free diagnosis" and it didn't fix the problem.
I ran into my High School auto shop teacher a few months ago and I thanked him for teaching us to never overlook the basics. You guys would be surprised at how one crappy ground or a vacuum leak can trigger a myriad of codes and drivability issues, yet there's still guys that shotgun parts at a problem because that's the code I got from my $20 Amazon code reader.
I loved what I did, I still dabble in it for a used car dealership my friend owns and I also do part time wrenching for a local landscape company and a horse farm.
What I don't miss is the corporate politics and greed that is killing the industry.
