I feel like that is a self-perpetuating cycle. Japanese carmakers build cars to rust out in half a decade and thus nobody wants to buy old rustbuckets thus the carmakers don't bother to build them to last.
It is a actually a legal and insurance issue in Japan. The costs are not tied to the quality of the vehicle. If it costs more to recertify a perfectly functional used vehicle than lease a brand new one, it makes sense to opt for new one.
A HUGE reform to our “throw-away 1 ton of iron” culture of ecology in Europe would be to rewrite the insurance estimates of cars.
The fact that insurances value a car of 35k€ at, I’m guessing, 25k€ at the exit of the garage, then 18, 12, 7, 4, 2k€ the following years, means that people see no value in used cars.
Whereas the real value of a car is certainly 25, 24, 23, 22, 21, 20k€ along the years, and when one recycles it, it’s actually a huge new cost for the household, for a car that could last 20 years. It breaks after 7 years? “Yeah buying a differential costs more than the entire price of the car, sir.”
But it isn't the insurance that defines the price,it is the sales market. It doesn't matter if insurance says it is worth 20k if people will only pay 2k
This was true in the 60s and 70s for Jap cars, they didnt make them to rust, they just didnt rust prevent like they do now. Go watch youtube and watch some rust belt mechanics like south main auto and u will see what what cars rust and what cars last now (hint, US made cars dont even last 10yrs with salt)
I personally drive a jap car from the 90s and 400+k on the clock. I can fix everything myself including rebuilding anything i need. My wipers arnt controlled by a CANN BUS, they use a simple mechanical switch. There is a new killer on the block that makes corrision look like childs play - its called computers. Cars these days are literly THROW away with the amount of electronics on them. Replacing the guage cluster on a new econo-car like a hyuandi can cost upwards of 8k. Instance write-off, doesnt matter that the engines wont lost 150k, because the electronics that manage it are discontinued way before that. Got a broken wire in your loom? thats 5k to replace.
