I mean, I'm pretty sure cars' lifespans have generally increased over the years, despite not being able to easily tweak valves or what have you. So many older cars don't have a 6th digit on the odometer because it was so common for a car to die after about 100,000 miles anyway. Now you might hit some issues, but that kind of mileage is basically your car's equivalent of a person's 40th birthday.
Yes, technology does march forward. That doesn't change the fact that many cars you're not even allowed to touch yourself, even the few things you can fix that don't require expensive speciality tools.
That would be a problem... If it were a thing. At least here in the US, it's not. Can you tell me where you're not allowed to fix your own car, assuming no specialty tools are needed?
The only item in my Honda (that I am aware of) that requires dealership attention is calibrating the "Honda Sense" sensors if they get replaced. And that is because the equipment required is so expensive, only the dealership carries it.
Plus, the only time I needed that was when I was hit by someone and the sensor was replaced because the panels were replaced.
I can still do all the minor maintenance myself, it is just a LOT more convenient for me to let my mechanic do it.
You can find service manuals online. I found the full blown 1,397 page OEM service manual for my '97 Prelude. For free. And failing that, there's probably a YouTube video for it, especially if it's not something incredibly rare.
The keyword is right there: 97. Anything after ~2014 and it's a mess to find manuals, for older stuff i was able to easily find manuals and fix them no problem
I’llbe 100% honest, bud, but if you can’t find a service manual on the internet or simply ask at the dealership I probably wouldn’t trust you to do the work. They’re available, just try even a little. And boy if you trust what little information may or may not be in an owner’s manual…
Besides, the only reason that info was in there was because the valves needed much more frequent adjusting. You really shouldn’t miss not needing to have that information so readily available.
