If you change all the rubber parts (orings, dampers, hoses etc) and service everything in time, don't you think a good big modern car can live a lot longer. The only annoying thing will be the furniture noise that inevitably appears, and the interior that gets worn.
I just restored an old Volvo S70 from 1998 and it's almost like new. 200 000 km, I expect 300 000.

I find the foam used to pad things wears out a bit before disintegrating. A Buick of mine had the ceiling foam fail and the fabric kind of looped down.
Many manufacturers pretty much want nothing to fail during the warranty period, but after that....
I did have one dealer put battery acid in my power steering pump, I had the car 3 years and just under 200,000 miles. The abrupt change in steering feel and the color change gave it away. Drained and refilled a bit of a bother, but it worked adequately after that till it got replaced at 264,000 miles.

The so called Pennsylvania grade crude oil is different than the Asphaltic crude normally used. Until recently the oil was preferred as the PA stuff congealed to waxy residue as opposed to the others tar like gunk.
They haven't sold me a car since then. Pretty hard mistake to make.
Long ago VW had the windshield wiper fluid container easy to confuse with IFR the brake fluid or was it the radiator? Not a good design.
Richard,
This is not the case, if you are so interested, please read my TechBrief at:

I am a card carrying member of the STLE (Society of Tribologists and Lubrication Engineers) and have designed lubricants and additives for several purposes as well as having traveled giving seminars on ICE lubrication.
Cheers!

I majored in both CE and EE in college, atomic attraction and tribology have always been an interest of mine as well. It is fascinating how adhesives and paints adhere or don't, and conversely how so many different forms of lubrication work or don't. The subject is not entirely as simple as one may think. A great book on this subject is 'Molecular Adhesion and it's Applications" by Kendall...

You have just become my new best friend...
I will eventually be pinging you for information regarding horology lubricants.

I hear you, I live on a hobby horse farm and just the maintenance overhead threatens to be all consuming: broken fence posts and wires, fence charger repair, bush hogging, manure spreading, tractor maintenance, outdoor water system maintenance, barn repairs and the list goes on...fortunately my wife is a vet so horse and tack care is her job...
Cars are much lower maintenance and can be turned off and parked.

Reminds me of a scene from Annie Hall.
I once was at a wine tasting and a guy across the table made a comment about the correct way to freeze and thaw fish and I disagreed with him. It turned out he was a PhD physicist specializing in cryogenics and a consultant to the Navy Department on preparing sailors mess.I spent 5 years studying grease at my last job. I learned that I don't know anything about grease, after the 5 years.
There is so much information, the specifics for each application are different, etc etc,
No wonder people spend entire careers studying lubrication.
I found it to be fascinating.

Yes mostly in tube amps, so you like the distorted soundfield created by amplifier short falls.
SS amps too are sensitive to load, e.g. an expensive one here.
Of course, adding a ton of GFB will fix this, while creating other problems. Again, this is not the whole truth, so don't blindfold yourself.
I deeply love this.
You can easily substitute "grease" by anything you fancy, or simply: "The more I learn, the less I know".
PS.: just to make sure: this is a praise!

And others insist on distorted soundfield created by transducer short falls. It's called hifi.
