alt Hacker NewsWhen I bought my 8 year old car, it was from the Midwest and the mechanic I asked to check it out said "Don't buy - it's got a good amount of rust because of the salt they use". I asked whether it means the car is less safe. He said "No, just more repairs and potentially costlier repairs. I said "Over the remaining life of the car, how much extra would it cost?" In today's dollars, the answer was $2000.
I bought the car. It easily lasted another 7 years before it died in a collision.
My car prior was a purely Midwest car, and I rarely washed it. It happily lasted 16 years. I passed it on to someone else, and he used it for a few more years.
I suspect the fear is overblown.

I've always lived in the midwest. Every car I've ever owned has been a car from the midwest, and has been driven in the midwest.
The salt from the road is driven by car tires into a briny mist that coats everything. It blocks vision through windows. It accumulates in chunks that can be kicked (like mud also can, except corrosive). It wicks its way into tiny crevices and betwixt layers and infects every part of the car that can be infected, and once there it rots everything that it can rot.
And I don't mean just the bodywork; that part has been getting better with improved processes and paint.
But stamped control arms often rust away while the ball joints and bushings are still in good form. Electrical connections rot. Frames and frame-like components often have scaly holes in them. Every exposed engine part corrodes; uncoated steel turns black, red, or brown; galvanized and aluminum parts turn white and kind of fuzzy (and stuck). Our junkyards are full of rusted-out hulks of cars with drivetrains that still work properly, even if they're ugly.
Fixing things when they break is tedious and time-consuming, and the most-sane approach to any repair on a car that's more than a few years old is to go into it with an expectation everything that doesn't crumble from rust is instead frozen with rust.
The work itself unilaterally causes a person a learn new facets of their verbal and mechanical vocabulary that they never even knew possible, and is arduous in ways that would test the emotional stamina of a Buddhist monk.
With enough cleaning and care (and just rinsing things off by driving in the rain), a car that is from the midwest can be largely saved. Getting rid of all of the salt slows the process down very dramatically.
But a car that is regularly driven in the midwestern winter is in the midst of a fairly quick process of being returned to the earth.
It's just a fact that is plain and that we live with every day. We do work to prevent it; on a warm-ish day in January, cars will line up around the block to get into a car wash and have a chance to dry out before ice freezes every orifice closed.
But it's not fear, I don't think. Just as we accept the sun coming up every day and disappearing over the opposite horizon every night, we accept the rot as something that will inevitably consume the most expensive machine that we own and that this will happen on a schedule that we play very little part in controlling.
Watch the channel Auto Parts City on YouTube, I assure you it is not overblown. It's a junkyard owner. A ton of cars come through there that run fine and could otherwise be very serviceable, but the frame/body are crumbling from rust, so they have to be crushed. We're talking cars that are 10 years old. And yes, it even includes Toyotas and Hondas. (In fact they're more likely to end up crushed for that reason than another car is, since a Nissan or Hyundai's transmission and engine won't last long enough for rust to really end its life.)
From a certain perspective, maybe some people don't care if they would be getting rid of the car in like 5 years, but if you do want to keep a car 15 years and you live in "salt country" I would strongly suggest doing something about the salt regularly.
Coincidently I was thinking about car wash just few days back, One was bought in 2014, never car washed seems fine so far. Another was bought in 2022 again no wash so far and no plan to.
I used to think everyone does it, I will do at some point but that point never came. Inside we vacuum and wipe every few months. Washed mats once in an year or so but car body wash rain takes care of it.
I saw rusted out cars and trucks all over the place when I visited northern Minnesota and the UP of Michigan last year. Even late-model cars that couldn't have been more than 5-10 years old had rusted out rocker panels.
The fear may be outdated.
I'm 62, and grew up near Detroit. I remember cars developing major rust holes after just a few years. The rusting also affected the inside of the engine compartment, and it did make repairs more difficult. There was an industry of aftermarket rustproofing shops, that were a scam. Every teenager with a car (which was still rare) learned how to patch rust holes with Bondo.
My first car, the frame rusted out and had to be welded back together.
Toyota and Honda put a stop to that. They did a number of things: Better steel alloys, better coatings, painting the bodywork before it could start rusting, eliminating places in the body where water could accumulate, etc.
Today, you rarely see totally rusted out cars on the road.
