The pickup I use as my daily driver has 310,000 miles on it. It never would have lasted that long without steady maintenance and tuneups, which has a different meaning than it did in 1975.
But to the throwaway generation that we have now they just drive it until it dies and then get a new one.
My 2018 truck has more electronic than mechanical complements. I should have spent the same amount of money on a perfectly restored 6th or 7th gen F150.
