I think the big part with cars is people want the new shiny thing.
The only people I’ve ever met who didn’t trade in a for shiny and new were my fellow cheap bastardin’ mechanin’ types who just don’t care.
Plus, too many people think cars must be serviced at “stealerships”, and I’ve seen what those lying bastards tell people their cars need. Like a 2 year old Toyota with 25,000 miles needing $4000 of engine leak repairs. On an engine that Toyota has manufactured since the 80’s…they don’t leak, they don’t even die. Hell, they still use a timing chain rather than a belt, so that’s maintenance it’ll never need.
Csrs don’t need replacing anywhere near as often as most people replace them. As I said elsewhere - my current daily driver is 18 years old, everything still works. It’s required very little regular maintenance over its life. Transmission was replaced at 200,000 only because a cooling line leaked into the transmission, which destroys the clutches eventually (it went 50,000 miles after the line failure, even towed stuff at max load).
Having worked on and had every major brand (and some obscure ones) in my family, there’s a reason Japanese cars are considered the most durable.
We’ve driven numerous Toyotas and Hondas 300k+. Some we still have, 30 years old or more.
Working on Toyota and Honda is generally much easier and far less frequent than other brands.
You can see how American car companies enshittify things when there’s a joint platform (Ford/Mazda, GM/Toyota, Chrysler/Mitsubishi). Invariably the American version is inferior, and even the Japanese company version often suffers with some of the same shitty design/engineering choices.
I refuse to ever again own an American vehicle, or even one of the joint platforms. I’ve had both - they suck to work on, require more frequent repairs, sometimes to things that just never fail on Japanese cars (especially electronics and control systems… Looking at *you" Jeep/Chrysler).
A car shouldn’t just have a life span of 6-10 years.
They don’t.
My current daily driver is 18 years old. I expect at least another 10 barring an accident, maybe 30 more years as a spare vehicle. It got a new transmission at 200,000 miles. Engine seems like it’ll make it to at least 400k. A replacement is $1500, far less than a new car.
Most cars in my family (approximately 30 cars) are between ten and thirty years old.
I’ve had 3 cars since 1996, all bought used, and I traveled for work with one. One car I sold to a family member, and it’s still being driven.
It’s people that choose to not drive cars this long.
